MAINTENANCE 633GC OPERATOR’S MANUAL

AIR FILTER

IMPORTANT

The air filter is made from a nylon micro mesh air filter and an internal spit-back screen. Both must be kept clean for the engine to operate properly. If the saw is not reaching full RPM, most likely one or both of the air filters are dirty.

•The air filter (Figure 1) should be free of holes and white in

color.

•	Replace air filter when dirty.
•	The spit-back screen (Figure 2) should be free of holes and be
	white in color. Clean with mild solvent or gasoline and dry with
	high pressure air. If spit-back screen is dirty the saw will not
	reach full RPM.	Figure 1

•During re-assembly, tighten air filter wing-nut "finger tight" plus an 1/8" of a turn with wrench.

STARTER HOUSING ASSEMBLY

IMPORTANT

It is common for concrete slurry to get inside the starter housing assembly during cutting. This can cause the starter pawls to stick and not engage when the rope is pulled.

Oil port

•After each usage, thoroughly flush the starter housing

assembly with water.

•Oil the recoil spring by spraying lightweight oil into the port

(Figure 3).

• Oil the starter pawls by spraying lightweight oil into the starter housing through the vents.

• Check the starter cord for fraying, replace if necessary.
