SPARK ARRESTER WARNING TO RESIDENTS  
OF CALIFORNIA AND SEVERAL OTHER STATES  
Trimmer Head Control Bail  
Engine Throttle Control Lever  
Under California law, and under the laws of several  
other states, you are not permitted to operate an inter-  
nal combustion engine using hydrocarbon fuels on  
any forest, brush, hay, grain, or grass covered land; or  
land covered by any flammable agricultural crop with-  
out an engine spark arrester in continuous effective  
working order.  
Handlebar  
Height Adjuster  
The engine on the unit is an internal combustion en-  
gine which burns gasoline, a hydrocarbon fuel, and  
must be equipped with a spark arrester muffler in con-  
tinuous effective working order. The spark arrester  
must be attached to the engine exhaust system in  
such a manner that flames or heat from the system  
will not ignite flammable material. Failure of the  
owner/operator of the unit to comply with this regula-  
tion is a misdemeanor under California law (and other  
states) and may also be a violation of other state  
and/or federal regulations, laws, ordinances or codes.

the discharge at anyone.  
Do Not:  
Do not mow near drop-offs, ditches, or  
embankments. You could lose footing  
or balance.  
28. Never run the engine in an enclosed  
area. Engine exhaust contains carbon  
monoxide, a deadly gas that is odorless,  
colorless and tasteless. Always run the  
engine outdoors where there is adequate  
ventilation.  
17. If using machine in wet conditions,  
exercise extreme care to prevent loss of  
footing. Wear footwear that will improve  
traction. Avoid sloping ground. Hold the  
handlebars with two hands and walk;  
never run.

be hot from operation. Allow parts to cool  
completely before inspecting, cleaning or  
repairing the unit.  
8. Never make adjustments or repairs  
while engine is running.  
g) Leave 1/2" air space at the top of  
the fuel tank to allow for fuel ex-  
pansion.  
9. Components subject to wear, damage  
and deterioration could expose moving  
parts or allow objects to be thrown.  
Frequently check components and re-  
place with factory recommended parts,  
when necessary. Regularly inspect the  
trimmer head and debris shield. Make  
sure they are not bent, damaged, or  
loose.  
14. Maintain or replace safety and in-  
structional decals. Refer to the Parts List  
for replacement decal information.  
2. Never run the engine inside a closed  
area.  
3. Never clean, or make adjustments or  
repairs with the engine running.  
Disconnect the spark plug wire and keep  
the wire away from the plug to prevent  
accidental starting. Remove key on elec-  
tric start models.  
15. Use only original-equipment replace-  
ment parts. Parts manufactured by oth-  
ers could present safety hazards and af-  
fect performance even though they may  
fit on this trimmer/mower.  
10. Only use eighteen-inch long .130" or  
.155" diameter trimmer line. Never use  
other lengths, diameters or material as  
trimmer line.  
16. Rememberthe end of the season is  
a good time to inspect equipment prior to  
storage.  
4. Keep all nuts and bolts tight, espe-  
cially the trimmer head attachment bolts,  
and keep equipment in good condition.  
Check mounting hardware on trimmer  
head every time you change trimmer line  
and prior to each use.  
17. To guard against engine overheating,  
always keep the engine debris guard  
mounted and clean.

Engine Throttle Control Lever to adjust  
the turning speed of the trimmer head.  
HOW TO USE TRIMMER HEAD  
CONTROL BAIL  
The Trimmer Head Control Bail (A, Figure  
4-3) is used to start and stop trimmer  
head motion.  
Figure 4-4: Control bail engaged.  
WARNING  
3. Once the trimmer head is revolving,  
push the unit forward to trim.  
If the trimmer head control bail is not  
operating properly, shut off the  
engine, disconnect the spark plug wire  
and move wire away from plug.  
1. Leave the control bail in the disen-  
gaged (released) position when starting  
the engine to prevent the trimmer head  
from turning when the engine starts. See  
Figure 4-3.  
To Stop the Trimmer Head  
Let go of the Trimmer Head Control Bail.  
Adjust or repair the control bail before  
using the trimmer/mower.  
To Stop the Engine  
2. When the engine is running, pull and  
hold the control bail up against the han-  
dlebar (Figure 4-4) to start rotation of the  
trimmer head.  
Put the Engine Throttle Control Lever in  
the STOP position. (If time allows, first  
move throttle lever to SLOW setting be-  
fore stopping engine.)  
Failure to follow this instruction could  
result in personal injury or property  
damage.  
3. Let go of the control bail to stop the  
trimmer head. The control bail should  
spring forward to the disengaged posi-  
tion. If it doesnt, do not use the machine  
until the control bail has been repaired.  
OPERATING THE MACHINE  
NOTE: If unit is operated in a station-  
ary position with the wear cup in con-  
tact with dry vegetation, significant  
heat will result that may deform the  
plastic spindle or scorch vegetation.  
Once you have read and understood the  
sections in this Manual on Safety,  
Assembly, Features and Controls, and  
Operation, you are ready to start and

Section 4: Operation 9  
Clean Unit Frequently  
Use Correct Walking Speed  
Use a travel speed that is suitable for the  
mowing conditions. Youll get better re-  
sults at slower walking speeds if the  
growth is tall or lush. Shorter or less  
dense growth can be cut at faster walking  
speeds.  
WARNING  
THROWN OBJECT HAZARD!  
Clean under the mower deck frequently to  
remove any grass buildup. Also clean  
around the muffler and on top of engine.  
See the cleaning instructions in Section  
5: Maintenance.”  
Objects such as rocks, pebbles, and  
small debris will be thrown violently  
by the cutting head, resulting in sig-  
nificant hazard to eyes and exposed  
body parts.  
Do Not Let Trimmer Lines  
Become Too Short  
Always wear safety-approved eye pro-  
tection and suitable clothing and  
footwear.  
Vary Throttle Speed For  
Conditions  
The vast majority of trimming and mow-  
ing jobs will yield the best results if the  
engine throttle is set at the fastest engine  
speed.  
Once the trimmer lines are worn to less  
than 1/2 their original length, trimming  
jobs begin to take far longer than they  
should. As a general guideline, once line  
length becomes half of its original length,  
its time to change to new lines.  
Keep children, pets and bystanders  
50 feet away from machine while  
operating.  
Be alert to hidden obstacles.  
Less demanding jobs (and projects that  
require very precise cutting) will yield  
better results if the engine speed is  
backed off somewhat. (For example,  
damage to trees and shrubs can be  
avoided by reducing the engine speed,  
using the lighter .130" diameter line, and  
by keeping a safe distance away.)  
Failure to comply could result in  
injury or property damage.  
Use Extreme Caution on Slopes  
When operating on sloping ground, use  
extreme caution and common sense to  
avoid possible injury or property damage.  
When mowing, let the cutting head rest  
lightly on the ground and do not lift up or  
push down on the handlebars. This tech-  
nique allows the cutting head to follow  
the ground contour closely, resulting in  
the most even cut possible. Also, be sure  
to ease into heavy growth to prevent  
overwhelming the machine.  
Do not mow on excessively steep slopes!  
Avoid slopes if greater than 15o or wher-  
ever footing is unsure. If a slope is diffi-  
cult to stand on, it is probably too steep  
to trim or mow. In this case, it may be  
wiser to establish a permanent ground  
cover on this area.  
Again, once you begin a particular job  
and get a feelfor the conditions, you  
will be able to make adjustments for the  
best possible results.  
Trim When Wet or Dry  
Keep Mowed Side to Your Right  
as You Move Ahead  
The unit feeds cut materials to the right  
side. Stay on the right side of unmowed  
growth as you move along.  
Do not trim on slopes when the ground is  
slippery. Trim across the face of a slope,  
not up and down. Slow down and exer-  
cise caution when changing direction on  
slopes.  
Grass and most other materials are most  
efficiently trimmed when dry. But the  
unit will do a fine job even with damp or  
wet materials. When conditions are  
moist or damp, be sure to clean debris  
off the machine regularly to keep cutting  
efficiency high. And watch your footing!

the spindle shaft. Note that the dished-in  
side of the belleville washer must face the  
flat washer. Tighten the nut securely  
(torque to 50 ft./lbs.), while checking fre-  
quently to ensure that the spindle head  
rotates freely. If the spindle head binds,  
it could be due to the belt being pinched  
between the spindle head and the belt  
guides. If so, remove the spindle head  
assembly and repeat steps 5-7.

start models.  
WARNING  
Failure to follow these instructions can result in serious personal injury or property damage.  
CHANGING TRIMMER LINES  
WARNING  
When trimmer lines wear, it takes longer  
to complete mowing and trimming pro-  
jects. A good rule of thumb is to change  
the lines when they reach half their origi-  
nal length.  
Offsetting the trimmer lines causes the lines to rotate faster than when they project  
an equal length on each side. This increases the chance of loose materials being  
dislodged and propelled at high speeds.  
Failure of the operator to wear safety goggles and appropriate clothing and to keep  
bystanders away can result in severe personal injury or property damage.  
Use the extra-heavy duty (.155" diameter)  
line when cutting thick, tough growth.  
Use the thinner (.130" diameter) line for  
less demanding conditions and for use  
near trees or shrubs to help prevent  
girdling (cutting of bark).  
Figure 5-8: Use this single line,  
easy-loop pattern for all but the  
more difficult cutting conditions.  
To Change Trimmer Lines:  
1. Stop engine, allow all parts to stop  
moving and then disconnect the spark  
plug wire. Remove the ignition key on  
electric start models. DO NOT touch the  
metal wear cup on the bottom of the  
spindle headit may be hot.  
NOTE: The two line holders on the trim-  
mer head are permanently secured. Do  
not attempt to remove the line holders.  
Figure 5-9: If lines tend to  
Reverse Loop  
loosen (especially in more diffi-  
cult cutting conditions), add a  
single reverse loop and then  
readjust line so that ends are  
even. This pattern results in a  
slightly narrower cutting swath.  
2. If necessary, you may tip the unit  
back slightly when changing lines.  
However, do not tip the unit all the way  
back as motor oil may flow to the exhaust  
area and the engine may smoke for sev-  
eral seconds when started.  
3. Three different line installation pat-  
terns are available, as shown in Figures  
5-8, 5-9 and 5-10.  
Figure 5-10: For more difficult  
cutting conditions, use two of the  
thicker (.155" diameter) lines in  
each line holder. Follow the  
pattern shown in Figure 5-8.  
4. Feed the line through the loops of the  
line holder as shown.  
An equal amount of line should project  
out from each side of the line holder,  
creating an overall 22" wide cutting  
swath.  
You may offset both trimmer lines  
somewhat to increase the cutting swath  
up to 25" wide. However, DO NOT off-  
set the line so that the overall cutting  
swath is greater than 25". See Warning  
statement at right.  
Whether replacing one or both lines,  
they must both be .130" or .155" in  
diameter.
