MAINTENANCE
AIR FILTER
The air filter is made from a nylon micro mesh. It must be kept clean
for the engine to operate properly. If the cut-off saw is not reaching
full RPM, most likely the air filter is dirty.
• The air filter (Figure 1) should be free of holes and white in color.
• Replace air filter when dirty.
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.
• After each usage, thoroughly flush the starter housing
assembly with water. (Figure 2)
• Lubricate the starter pawls by spraying light weight oil
into the starter housing through the vents. (Figure 2)
• 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 3). 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
