Fuel Filter and Fuel Pump Service
WARNING
Many solvents are highly flammable and may
cause serious burns. Improper use of sol-
vents can result in fire or an explosion. Do
not use gasoline or low flash-point solvents
to clean the fuel filter and/or the fuel pump.
Clean only in a well-ventilated area away
from sources of sparks or flame, including
any appliances with a pilot light.
•
The fuel filter can not be disassembled. If the fuel
filter gets clogged, replace it with a new one.
The fuel pump can not be disassembled. If the fuel
pump fails, replace it with a new one.
Cooling System Cleaning
Before each use, check that the air inlet (rotary)
screen (G) is free from grass and debris and clean if
necessary. When checking or cleaning the air inlet
screen, loosen the screws (B) and remove air inlet
guard (A). Every 50 hours of operation, check dust or
debris inside fan housing. To check inside, remove
the cleanout covers (H) and see inside from the in-
spection ports of fan housing. Clean or blow the
dust if needed. If it is difficult to clean the dust with
the ports, remove the fan housing and clean the dirt
completely. Every 100 hours of operation, check and
clean the cooling fins and inside of engine shrouds to
remove grass, chaff or dirt clogging the cooling sys-
tem and causing overheating. When cleaning, re-
move the air cleaner (F), guard (A), loosen the bolts
(P), inlet screen (G), loosen the bolts (D) (E), and
then, remove the fan housing (C).
NOTICE
Do not run engine before all cooling system
parts are reinstalled to keep cooling and car-
buretion as intended.
[Recoil Starter Model]
When checking or cleaning the air inlet screen (O),
loosen the bolts (J) and remove the recoil starter
