Bar Oil (continued)

Oil Pump Adjustment

Guide bar and saw chain lubrication is auto- matically provided by an adjustable-rate oil pump designed to operate whenever the clutch drum rotates. A temporary increase in oil flow rate is often desirable when cutting hardwoods or large-diameter softwoods, and can be provided as follows:

1.Stop the engine and verify that the engine stop switch is in the “OFF” position.

2.Place the saw on its side, with the clutch cover facing up.

3.Use a screwdriver to turn the oil flow rate adjustment screw:

a.Clockwise to decrease bar and chain lubrication.

b.Counter-clockwise to increase bar and chain lubrication.

Starting the Engine

WARNING!

This chain saw is equipped with a fast idle feature for ease of engine starting. When the fast idle is set, the saw chain will rotate when the engine starts! Rotating saw chain can cause serious injury. Clear a safe work area before starting the engine.

NOTE:

This engine ignition system is controlled by a two-position “ON-OFF” switch labeled “I” for ON and “O” for OFF located near the rear handle.

IMPORTANT!

This chain saw is equipped with a throt- tle trigger lock out system designed to prevent unintended throttle activation.

This system requires the operator to first depress the throttle lock out lever on top of the rear handle to release the trigger from the engine idle position.

Engine Start:

1.Move the ignition ON-OFF switch to the ON position.

2.COLD ENGINE ONLY: Completely close the choke by pulling the choke control out to the fully extended posi- tion. This motion will automatically engage the “fast idle” setting.

3.WARM ENGINE: Pull the choke con- trol out to its fully extended position and then push the choke control all the way in again. This motion will automati- cally engage the “fast idle” setting.

8.When the engine attempts to start or starts, push the choke control in if pre- viously set. If the engine does not con- tinue to run, pull the starter until the engine restarts then immediately press and release the throttle lever to disen- gage the fast idle.

CAUTION!

The recoil starter can be damaged by abuse!

■■Never pull the starter completely to the end of the starter cord. Fully extending the starter cord can damage the starter spring, cord and/or starter assembly.

■■Never release the starter grip with the starter rope extended. Always hold on to the grip during engine start and return the starter grip back to the starter housing slowly as the starter spring retracts the cord.

NOTE:

If the engine fails to start, repeat the starting procedure setting the choke control appropriately for either a cold or warm engine. If the engine still fails to start, refer to the section, “Starting a Flooded Engine.”
