HS81 CUT-OFF SAW — INITIAL START-UP/OPERATION

INITIAL START-UP

CAUTION

DO NOT attempt to operate the saw until the Safety, General Information and Inspection sections of this manual have been read and thoroughly understood. Depending on engine manufacturer, operating steps may vary. See engine manufactures operating manual.

CAUTION

NEVER operate the saw in a confined area or enclosed area structure that does not provide ample free flow of air.

ALWAYS wear approved eye and hearing protection before operating the saw.

NEVER place hands or feet inside the belt guard or blade guard while the engine is running. ALWAYS shut the engine down before performing any kind of maintenance service on the saw.

Explosive Fuel

Fuel Check

Motor fuels are highly flammable and can be dangerous if mishandled. DO NOT smoke while refueling. DO NOT attempt to refuel the saw if the engine is hot! or running.

1.Remove the fuel cap located on the side of the saw.

2.Visually inspect to see if fuel level is low. If fuel is low, replenish with fuel oil mixture as shown in Figure 22.

3.When refueling, be sure to use a strainer for filtration. DO NOT top-off fuel. Wipe up any spilled fuel.

This saw uses a 2-stroke engine which requires a mixture of premium 92 octane

NOTE unleaded gasoline and smoke free 2-stroke motor oil. See Figure 22.

Figure 22. Fuel to Oil Mixture

For correct fuel to oil mixture, add 2.6 fl. oz (29.6 ml) of 2-stroke motor oil to 1 gallon (3.8

NOTE liters) of premium 92 octane unleaded gasoline. For a 5 gallon can of premium unleaded gasoline add 13 fl. oz (384 ml) of 2-stroke motor oil.

A bottle ( 2.6 fl. oz) of smokeless 2-stroke motor oil cannot be purchased separately.Only a case of 36 individual bottles can be purchased. When ordering use Multiquip P/N 00325.

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

NOTE engine. The OPEN position provides the correct fuel mixture for normal operation after starting, and for restarting a warm engine.
