5-2. TO START ENGINE

1. Press red STOP switch to the "I" ON position for start-
ing (Figure 5-2A).
2. Pull the choke (A) out as far as it will go until the choke
stays out. (Figure 5-2B). This advances the throttle so
you do not have to hold trigger while starting.
3. Push the primer bulb (B) 10 times (Figure 5-2C).
4. Place saw on a firm flat surface. Hold saw firmly as
shown (Figure 5-2D).
5. After pulling rope 4 times, move choke lever (G) all the
way in (Figure 5-2E).
6. Hold saw firmly and pull rope until saw starts-perhaps
4 more pulls.
7. Warm up for 30 seconds. Depress the safety latch and
squeeze and release the
throttle trigger (H) for idle (Figure 5-2F).
8. If engine failed to start, repeat these instructions.
IMPORTANT IDLING INFORMATION
In some cases due to operating conditions (altitude, tem-
perature etc.) your chain saw may need a slight adjustment
to the idle speed.
After warm up - See the User's Manual section 5-2, step 7
- If unit does not Idle after restarting 2 times, follow these
steps to adjust idle.
1. Idle adjustment access (J). (Figure 5-2G)
2. Using a Phillips or slotted screwdriver - turn screw 1/4
to 1/2 turn clockwise (to the right). Unit should then
idle properly. (Figure 5-2H)
NOTE: If chain turns while idling - turn screw back to the
left until chain stops and unit continues to idle.
