2. With the throttle lever in the RUN position, increase  
the engine rotation.  
3. Push the travel lever forward slightly. This will cause  
the roller to travel forward at slow speed.  
Figure 24. Vibration Lever  
4. To increase the travel speed, push the travel lever  
further.  
CAUTION :  
Using vibration with clutch slipping causes  
the clutch to burn. Also, vibration should not  
be used over completely compacted area,  
paved road surface, or with stationary roller.  
5. Travel speed can be varied between 0 and 3 km/h  
(both forward and reverse).  
6. Push the travel lever backward to go in the reverse  
direction.  
WATERING  
CAUTION :  
1. For watering work, turn the water cocks clockwise, at the  
rear of the machine, to start sprinkling.(Figure 25).  
DO NOT reduce speed during work. When  
shifting travel lever from forward to reverse,  
be sure to stop the lever at the NEUTRAL  
position first before moving the lever to the  
opposite direction. DO NOT shift the lever  
from forward to reverse (or reverse to  
forward) in one motion.

SAFETY FEATURES  
1. A horn is provided to warn of approach.  
Bypass  
Valve  
Bolt  
2. The dead man device prevents accidental traveling  
in reverse. It automatically makes the travel lever  
return to neutral position by stopping the machine  
when an object comes in contact with the dead man  
device.  
STOPPING  
1. With travel lever in the neutral position, and the  
vibration lever in the off position, return the throttle  
lever to the START position. Allow the machine to  
cool down for 3 to 5 minutes.  
Figure 26 Location of BypassValve Bolt  
CAUTION :  
NEVER tow roller with any type of vehicle.  
2. Push the throttle lever forward to stop the engine. In  
a motor start, return the key switch to the STOP  
position as soon as the engine stops.  
Doing so will damage the hydraulic system.  
NEVER perform unloading procedure on a  
slope. This may cause roller to roll down if  
parking brake or blocking is deficient.  
CAUTION :  
Neglecting to return the key switch to the  
STOP position will cause the battery to  
discharge making start up impossible the  
next time.  
LIFTING  
1. Use a crane or lift to load and unload the machine. A  
skilled crane operator is required to perform the job.  
2. When lifting the machine, check for any damaged or  
loose bolts, lifting hooks, and shock mounts.  
3. After the engine stops, close the fuel cock.  
3. Check any damaged or loose bolts in the guard frame to  
avoid machine sliding off.  
4. Lock the parking brake by pulling the brake lever  
and rotating it 90 degrees clockwise.  
4. Make sure that the machine is shut off before machine is  
lifted.  
Parking brake system should  
always be kept clean to avoid  
mud deposits.  
5. Use reliable cable for lifting.  
6. ALWAYS lift the machine vertically and keep the  
machine away from workers and animals.  
7. DO NOT lift the machine higher than the required  
height.  
UNLOADING  
TRANSPORTING  
1. If you need to move the roller by pushing it manually  
once engine is stopped, loosen bolt of bypass valve  
on oil pump by one rotation counterclockwise. This  
will cause the hydraulic break to disengage and allow  
the roller to be moved more easily (Figure 26).  
1. ALWAYS make sure that the machine is shut off  
while being transported.  
2. Check that the fuel cap is properly closed and  
tightened.  
2. After moving, tighten the bolt again. Tightening torque  
is 55 to 70 kgf-cm.  
3. When traveling long distances or on rugged terrain,  
drain the fuel of the machine before transporting.  
4. Tie down the machine securely on the  
transportation so that it will not move or topple over.
