MAINTENANCE
AFTER EACH USE
1. After cutting, pull trigger to spin the chain for at least 15 seconds with the
water on to ush slurry and debris from chain, guidebar and drive sprocket.
2. Stop saw and wash concrete slurry from saw assembly with special attention
to the starter housing and ywheel. Do not let slurry dry on saw as it will be
very dicult to remove later.
3. Avoid getting any water in the carburetor or exhaust system. If water enters the
exhaust port, it can enter the carburetor. To make sure there is no water in the
exhaust system, assure the multi-function lever is set to “STOP” position, point
the guidebar tip down and pull the starter handle several times to expel water
from muer.
4. Remove the chain and guidebar. Flush out the chain tensioner and side cover
with water. Lubricate tensioner with waterproof grease.
5. After cleaning the saw, spray the entire saw body, chain, guidebar, and drive
sprocket with lightweight oil. Using lightweight oil on the saw will minimize rust
and help reduce slurry build up.
6. Inspect and tighten all fasteners as necessary.
7. Inspect drive sprocket for wear. Replace if tooth tips are pointed, or if groove
cuts through top of tooth.
8. Check clutch cup needle bearing for wear. Assure clutch cup spins freely and
without excessive play.
9. Check starter cord for wear or damage. Replace as necessary.
10. Inspect air lter. Replace lter if dirty or wet.
11. Spray lightweight oil into the air intake slots on the starter housing and ywheel
(this will prevent the starter pawls from sticking).
IMPORTANT
AFTER EVERY 10 HOURS OF USE
1. Remove the starter cover and clean the ywheel ns and the starter pawls with
a wire brush, then apply waterproof grease to the starter pawls.
2. Remove the spark plug and clean with a wire brush. Check the electrode gap.
The correct gap is 0.5 mm (0.020 in). Replace if necessary.
Maintenance
AFTER EVERY 40 HOURS OF USE
1.
Change the spark plug. Adjust the electrode to 0.5 mm (0.020 in).
2. Check the fuel lter located inside the fuel tank. Clean or replace if clogged.
