REGULAR CHECKS AND MAINTENANCE WORK68
BChecking Radiator Hoses and Clamps
To avoid personal injury:
A Wait long enough for the radiator coolant to
cool down.
Check the coolant hoses for proper connection. This
check should be carried out every 200 hours or every 6
months, whichever comes first.
1. Should the hose clamps become loose or coolant
leaks, tighten the hose clamps properly.
2. Should the radiator hoses become swollen, aged or
cracked, they must be replaced and the hose clamps
tightened again properly.
BInspection and Cleaning Air Filter Element
Open the engine hood and remove the dust-cover. Take
out only outer element, clean the element, case interior
and reassemble. During reassembly, take care to install
the dust-cover so that its TOP mark (arrow) faces up-
wards. Do not remove the inner element.
A Should the machine be used in extremely dusty areas,
the air filter element must be inspected and cleaned
more frequently than in the specified maintenance
periods.
A The air filter has a dry element, keep free from oil.
A Do not run the engine without the air filter.
