OPERATION
STARTING AND STOPPING A CHAIN-BASED CUT OFF SAW
Never start a chain-based cut off saw without the guide bar,
diamond chain and side cover properly assembled. The clutch may
come loose and cause personal injury.
Always move a chain-based cut off saw at least 10 feet (3 m) away
from the fueling area before starting.
Place the chain-based cut off saw on clear ground. Ensure that
secure footing is established and diamond chain is not contacting
any objects.
COLD ENGINE STARTING PROCEDURE
1. Toggle the ignition switch to the "ON" position and pull the
choke lever out.
2. Lock the throttle in the start position by depressing the trigger
(A) and trigger interlock (B) at the same time.
3. Depress and hold throttle lock button (C) while releasing the
trigger and trigger interlock in succession.
4. Press decompression valve (D).
5. Open the water valve ¼ turn.
6. Place the 613GC Cut-Off Saw on the ground making sure the
chain is free of any obstructions.

pawls engage.
10. Pull the starter cord (hard, fast, short pulls) until engine fires or
"pops" - should be 1 to 7 pulls.
11. Push the choke lever in.
12. Check decompression valve. Press if necessary.
13. Pull the starter cord until engine starts - should be 1 to 2 pulls.
