LUBRICATION AND MAINTENANCE
3. To shorten outer cable release the adjusting
screw of throttle wire.
4. Use the same procedure for adjusting
maximum speed on the foot throttle. Lock the
adjusting screw at full throttle pedal stroke.

VALVE CLEARANCE (LASH)
Correct valve clearance is one of the most
important factors of good engine performance.
Excessive clearance will cause the engine to
operate excessively noisy, and insufficient clearance
will cause poor performance. Because of this, it is
extremely important that care be used when
adjusting valve clearance.
Checking and Adjusting Valve Clearance: Check
and adjust the valves every 600 hours. The
clearance check and adjustment should be made
with the engine cold.
1. Remove the valve rocker arm cover.
2. With the engine idling, check the clearance of
each valve with a feeler gauge, Figure 58.
The setting should be
Intake 008 (.2 mm)
Exhaust 008 (.2 mm)
3. If the clearance is incorrect on any valve, turn
the adjusting screw at the push rod end of the
valve rocker arm either into or out of the arm
while checking for correct clearance with the
feeler gauge.
4. Install the rocker arm cover. Use a new
gasket if the old one is damaged. Tighten the
cover bolts evenly.

MAINTENANCE AND INSPECTION OF
THE ROPS
After the first 20 hours of operation and after every
500 hours of operation or six months, whichever
comes first, do the following
1. Check the torque of the ROPS mounting
bolts. If necessary, tighten the bolts to the
correct torque. See bolt torque’s page 55.
2. Check the operator 5 seat and the mounting
parts for the seat belt. Tighten the bolts to the
correct torque. Replace parts that show wear
or damage.
POSSIBLE DAMAGE TO THE ROPS
If the machine has rolled over or the ROPS has
been in some other type of accident (such as hitting
an overhead object during transport) you must
replace the ROPS to get the original protection.
After an accident, check for damage to (1) the
ROPS, (2) the operator’s seat, (3) the seat belt and
the seat belt mountings. Before you operate the
machine, replace all damaged parts.
IMPORTANT: Do not try to weld or straighten the
ROPS.
