MRH-800DS—OPERATION
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. Check any damaged or loose bolts in the guard frame to
avoid machine sliding off.
4. Make sure that the machine is shut off before machine is
lifted.
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.
TRANSPORTING
1. Always make sure that the machine is shut off while
being transported.
2. Check that the fuel cap is properly closed and
tightened.
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.
SAFETY FEATURES
1. A horn is provided to warn of approach.
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.
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.
Parking brake system should
always be kept clean to avoid
mud deposits.
NOTE
UNLOADING
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 23).
2. After moving, tighten the bolt again. Tightening torque
is 55 to 70 kgf-cm.
3. After the engine stops, close the fuel cock.
4. Lock the parking brake by pulling the brake lever
and rotating it 90 degrees clockwise.

NEVER tow roller with any type of vehicle.
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.
