Radiator fin cleaning
NOTICE: Beware dirt from air
W ear protective equipment such goggles protect your eyes when blowing compressed air Dust flying debris can hurt eyes.
Dirt and dust “DD” adhering the radiator fins (RF) reduce the cooling causing Make a rule check the radiator fins daily and clean
• Blow f dirt and dust from fins and periphery with compressed air ( 0.19 MPa ( psi ) less order not damage the fins).
• contaminated heavily , apply thoroughly clean and rinse with tap water shower
NOTICE: Never use high pressure water air from close fins never attempt clean using a wire Radiator fins (RF) can
V - belt tension check (The second time and after)
Check and adjust the V - belt tension.
Inspection and adjustment governor lever and accelerator
The governor lever (GL) and accelerating devices erating lever , the machine unit are nected accelerating wire rod. the wire becomes stretched the connections the deviation the position may result and make operation Check the wire periodically and adjust necessary not strongly move the accelerating wire accelerating pedal. may deform the governor lever stretch the wire cause irregular engine speed
Checking and adjusting procedure are follows:
• Check that the governor lever (GL) the engine makes uniform contact with the high idling (H) and low idling (LI) limiting screws when the ing devices are the high idling speed low idling speed
• either the high the low idling speed side does not make contact with the limiting screw , adjust the accelerating Loosen the accelerating wire fastening screw (AF) and just the wire contact with the limiting screw
NOTICE: Never loosen the limiting will impair the safety and performance the product and functions and result shorter engine
Air cleaner cleaning and element replacement
NOTICE: Beware dirt from air W ear protective equipment such goggles protect your eyes when blowing compressed air Dust flying debris can hurt
The engine performance adversely fected when the air cleaner element (E) clogged periodical cleaning after disassembly
• Undo the clamps (L) the dust pan (DP) and move the dust
• Loosen the wing nut the element and pull out the element (E)
