Engine maintenance
1. Service Air Filter
Service air filter every 80 hours
NOTE: Service more often under dusty conditions.
Remove filter cover ( See Fig. 35 ). Check the filter cover and the air filter, if the filter cover
and the air filter are dusty, please clear the filter cover and replace with a new air filter.
2. Engine Lubrication
2.1 Engine oil replacement
You must change the oil in the crankcase after the first 10 hours of operating of your new
engine and after 40 hours of use thereafter. That will insure proper lubrication of internal
parts and prevent costly repairs due to excessive wear. (See Fig. 36-38)
