DO NOT use automotive motor oil when adding oil to fuel. For optimum performance

NOTE and proper lubrication, the manufacture recommends that the fuel to oil ratio mixture be 25:1

A single bottle ( 2.6 fl. oz) of smokeless 2-stroke motor oil cannot be purchased separately. However you can purchase from Multiquip a case (P/N 00325) of 48 individual bottles or a 6 pack (P/N 003256PAK).

Starting

1.Place the engine ON/OFF switch in the ON position

2.Using your thumb, press down on the throttle lock lever, while squeezing the throttle trigger.This will lock the throttle in the half-throttleposition.

3.Pull the choke lever all the way out to the CLOSED position.

4.Pull the decompression button outward.

5.Place the saw on level ground. Make sure the saw blade is free to rotate and will not come into contact with any foreign objects.

6.Hold the front handle firmly with the left hand and put your right foot onto the base of the rear handle.

The CLOSED position of the choke lever enriches the fuel mixture for starting a COLD
