1. Slip steering wheel over steering shaft and align the wheel

hole with the shaft hole;

5. Secure by clipping an ‘E’ Clip into the groove on the pivot

rod. See Fig. 4.

2. Insert drift punch – partially through the holes to maintain

Fig.2.

INSTALLING THE BATTERY

BATTERY

3. Drive roll pin in until flush with the outside of wheel.

Remove Battery as follows;

(a). remove terminal cable from battery;

(b). undo wingnuts and remove clamp bar.

The battery is not filled with Electrolyte. This should be

done by adding 33% strength battery acid to each cell

until plates are covered. Electrolyte must be purchased

from a local battery supply outlet.

IMPORTANT: DO NOT OVERFILL BATTERY. ACID WILL

OVERFLOW INTO OTHER PARTS OF THE MACHINE AND

SEVERE CORROSION AND DETERIORATION WILL RESULT.

Fig. 3

Leave filler caps off and connect battery charger to

battery terminal. Charge at the rate indicated in the

instructions supplied with the battery.

FIT STONE GUARD

1. Slip spring into stone guard pivot rod so that the short leg

rests on top of the stone guard;

After charging, check that Electrolyte is still covering

plates, if not, add to correct level. Install filler caps.

2. Now twist the spring as shown and feed the end of the

pivot rod into the forward pivot bracket: See Fig.3.

Replace battery and secure.

Install the positive (red) cable to the positive (+)

terminal and the negative (black) cable to the negative

(-) terminal.

3. Insert the short end of the pivot rod fully into the rearward

pivot bracket;

Secure for good electrical contact.

4. Release the spring. It should spring down onto the top of

the cutter head and be tensioning the stone guard down;

BEFORE OPERATING

FILL CRANKCASE WITH OIL

FILL FUEL TANK – See Safety Instructions.

The rider mower may be delivered without oil in the

crankcase. Oil must be added before attempting to

start the engine.

Use only regular grade or unleaded petrol.

Do not mix oil with petrol – engine damage may result.

Clean around fuel tank cap so foreign matter cannot

enter tank when cap is removed.

1. Place machine on level surface. Ensure that the

oil plug is securely tightened. Clean around

dipstick.

Using a funnel, fill tank with regular grade or unleaded

petrol. Replace cap.

2. Unscrew and remove dipstick from oil filler tube.

Wipe up any petrol that may have spilled.

3. Insert funnel into filler tube and slowly add oil in

accordance with the engine manufacturer’s

direction.

CHECK TYRE PRESSURE

Check and maintain tyre pressure at 140KPA (20 PSI) front

and 96KPA (14 PSI) rear maximum.

NOTE: Avoid premature engine failure by ensuring

the funnel is clean so contaminants are not

introduced into the crankcase. Wipe any oil

spills so it will not cause dirt to collect on the

engine.

ADJUSTING THE SEAT

Tip the seat forward,

loosen the seat securing

screws. Relocate the seat

for operator comfort.

Tighten the seat securing

screws and lowers the seat

See Fig.5

4. Ensure oil level is at the full mark on the dipstick,

when screwed completely in. When finished

replace dipstick and retighten.

NOTE: See Maintenance Instructions.

OPERATING INSTRUCTIONS

AUTO – DRIVE OPERATION

Forward and backward movement of the mower is controlled by the drive selector pedal. As with a motor vehicle,

speed is controlled by the amount of pressure on the drive selector pedal. Ensure that the mower user is familiar with

this means of operation before operating the mower, particularly in tight or confined areas.

TO START ENGINE

NOTE: The engine will not start unless the cutter drive is

disengaged, and clutch/brake pedal is depressed.

ENGAGING CLUTCHES

When engaging the cutter drive lever or releasing the

clutch/brake pedal, always operate slowly. Do not use a

jerking motion. Moving these controls too fast could

possibly overload and stall the engine.

Depress clutch/brake pedal – Apply the parking brake

Move the drive selector to neutral

Disengage the cutter drive

Move the throttle lever to the choke position

Turn the ignition key to the start position and release

when the engine starts

WARNING: To avoid loss of control always come to a

complete stop before changing drive direction

and slow down before turning.

Move the throttle lever to about ¼ position

REMEMBER

Always look behind the machine before reversing

Do not refuel when the engine is running or while the

engine is hot

Keep bystanders away – Keep hands and feet clear of

moving parts

Keep machine clean of grass and debris

Keep all safety devices (guards and switches) in place

and working

TO MOW OR DRIVE

Depress clutch/brake pedal

Disengage the parking brake

Select height of cut

Move throttle to about ¾ position

Engage cutter drive

Select desired drive

Slowly release clutch/brake pedal to move off

Periodically check the machine and the cutting mechanism.

If parts are worn or need replacing do so by using only

Genuine Rover Replacement Parts.

TO STOP ENGINE

Depress clutch/brake pedal

Shift the drive selector to neutral

Disengage the cutter drive

Apply the parking brake

Move throttle lever to the slow position

Turn the ignition key to OFF. Remove the keys

There is a comprehensive Ranger Spare Parts List contained

in this book to help you select the right part quickly.

Before working on the mower, disconnect the spark plug lead

from the spark plug and place it where it cannot contact the

spark plug.

TO STOP IN AN EMERGENCY

Depress brake/clutch pedal and drive selector pedal

together. (This disengages power from the engine and

engages the disc brake)

Check your Rover Ranger frequently for loose nuts, bolts,

belts etc, and keep these items correctly tightened and

adjusted.

Apply park brake and lock

Move throttle to slow position and switch off ignition key

Dismount from mower if it is safe to do so

Note: A check after the first two hours of operation is

recommended. Engine failure or rapid engine wear

mainly result from the following causes –

Dirt or abrasives entering the engine via the air

cleaner due to –

a. The air cleaner element not being serviced

regularly, or

b. The air cleaner damaged or dislodged

Dirt or abrasives entering the engine via the oil

filler tube due to –

a. Using a funnel not cleaned of dirt and grit,

b. Topping up with contaminated oil. Oil stored

in an unclean container

IMPORTANT

1. The parking brake should always be applied before

leaving the machine

2. The parking brake must be released before attempting to

drive

3. Depress the clutch/brake pedal-when starting or coming

to rest

4. Do not use sudden directional reversal which can cause

wheel spinning

Lack of oil. It is important to –

a. Check the oil level regularly (every 5 hours of

operation)

b. Maintain a full sump

SPARK PLUG

The spark plug gap gradually increases during engine running

and should be checked periodically and whenever the engine

malfunctions.

NOTE: Nuts holding air cleaner cartridge must be installed

with fiber washers down on cartridge plate to

prevent dirt from entering carburetor. Tighten nuts

by hand. Over tightening could collapse cartridge.

Clean around spark plug area so that dirt will not enter

engine when plug is removed

NOTE: Petroleum solvents, such as kerosene, are not to

be used to clean cartridge. They may cause

MAINTENANCE

COOLING SYSTEM

The Ranger has an air cooled 4 stroke engine. It must be

cleaned frequently. Remove any build-up of grass, dirt or other

debris from the -

Cylinder;

Cylinder head cooling fins;

Cooling air intake screen and;

Carburetor governor levers and linkages.

This will ensure adequate cooling and correct engine speed.

THROTTLE CONTROL

Proper choke and stop switch operation is dependant on

adjustment of remote controls –

Loosen outer cable clamp screw (D) on engine; See

Fig.9.

Set throttle control to choke position;

Adjust outer cable under clamp plate so that choke is

operated;

Tighten clamp plate screw and check –

a. Choke does not operate in fast position,

and

Move throttle to the slow position and adjust the slow

running stop screw (B) to give an engine speed of 1700

to 1800 RPM.

Adjust the idle needle valve (C) slowly in (lean) and out

(rich) until engine idles smoothly.

Reset engine idle speed.

Check operation.

Engine should increase speed

without hesitation when throttle control is moved

quickly from slow to fast. If the engine tends to die out,

adjust the high speed needle valve 1/8 turn anti-

clockwise until engine accelerates smoothly.

Never tamper with the engine governor setting.

Changing the engine governor speed will void engine

warranty.

b. Stop switch operates correctly.

CARBURETOR ADJUSTMENT

The carburetor has been factory set and should only require

occasional fine tuning. See Figs.9 & 10.
