Maintenance Schedule - PowerLand PDL4000 Manual

When the engine starting, if at the unload, the rotation speed is instability, that indicates the
ratio between air and fuel (mixture ratio) is wrong, please loosen fixed nut on lid of the
reducer assy. like this can adjust gas-pressure adjusting screw. Clockwise adjusting can
increase the gas pressure, contrarily is reduce pressure. First slowly rotate gas-pressure
adjusting screw by clockwise and check run case of engine, let its rotation speed achieve the
best state, then screw nut. If after increase the gas pressure, the unload rotation speed also
not normal work, please adjust throttle fixing screw, let it normally work.(but when adjust
throttle fixing screw, please don't adjust more, because after unloading the load so as to
avoid excessive rotation speed caused).
When the engine starting, if often shake and bang, that indicate the gas amount excessive.
Please loosen fixed nut on lid of the reducer assy., and counterclockwise adjust
gas-pressure adjusting screw, let engine normally work, after finish the adjusting, then screw
nut.
Combustion gas flow adjust: The generator can adjust gas flow only under rated load state. If
adjust gas flow adjusting screw, it can change max load gas amount. Clockwise adjusting
can reduce gas flow amount; contrarily can increase gas flow amount. When clockwise
adjust, if the engine speed high, it indicates gas flow amount more, should continue
clockwise adjust; when the engine speed decline, it indicates gas flow amount too less,
should stop adjusting, and counterclockwise rotate 1/4 round. Contrarily, counterclockwise
adjust rotation speed to the highest point.
If more times start fail, and use reinforce handle also fail, the chief reason is that excessive
gas go into cylinder. If it is really reason, please close gas valve, and start generator, let gas
drain finish, and open gas valve, restart generator immediately.

Maintenance Schedule

Follow the service intervals indicated in the schedule below.
Service your generator more frequently when operating in adverse conditions.
