AIR FILTER
The air filter is made from water resistant polyester and includes
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.
IMPORTANT
STARTER HOUSING ASSEMBLY
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.
IMPORTANT
• After each usage, thoroughly flush the starter housing
assembly with water. (Figure 3)
• Lubricate the starter pawls by spraying light weight oil into the
starter housing through the vents. (A, B, C)
• Check the starter cord for fraying, replace if necessary.
STARTER CORD REPLACEMENT
• Remove the 4 screws that attach the starter assembly to the
crankcase.
• Pull the cord out approximately 8” and lift the cord up into
the notch in the pulley (Figure 4). Relax the recoil spring
by placing thumb on pulley and gently allow the pulley to
unwind entirely. Undo the screw in the center of the pulley
and remove the pulley.
• Thread the new cord through the starter cover and fasten
it to the pulley. Wind 4 turns of the starter cord on to the
pulley. Assemble the starter pulley against the recoil spring
so the end of the spring engages into the backside of the
pulley. Install the retaining screw in the center of the pulley.

MAINTENANCE
• 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.
