Ryobi Outdoor RY74003D manual Starting the Engine, Stopping the Engine, Preparing for Cutting

OPERATION

NOTE: Do not use dirty, used or otherwise contaminated oils. Damage may occur to the oil pump, bar, or chain.

1.Carefully pour the bar and chain oil into the tank.

2.Fill the oil tank every time you fuel the engine.

STARTING THE ENGINE

See Figure 8.

WARNING:

Keep your body to the left of the chain line. Never straddle the saw or chain, or lean over past the chain line.

1.Place the chainsaw on level ground and ensure that no objects or obstructions are in immediate vicinity that could come in contact with the bar and chain.

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

STARTING A COLD ENGINE:

See Figure 3 and 8 through 14.

3.Move the chain brake to the BRAKE position (B). See Figure 3.

NOTE: Set the chain brake by pushing the chain brake lever/hand guard forward (towards the bar), to the brake position. Refer to “Operation – Operating the Chain Brake” later in this manual for additional information.

4.Set the ignition switch to the RUN (I) position (A).

5.Fully press and release the PRIMER BULB (C) 7 times.

6.Pull CHOKE (D) lever all the way OUT to full position (E).

7.Engage trigger release (F).

While squeezing both the trigger release and throttle trigger (G), push in the throttle lock button (H). Release the throttle trigger. This latches the trigger for starting.

8.Pull STARTER (I) until engine attempts to start.

Slowly pull the starter grip out for a short distance until you feel the starter engage, then briskly pull straight up. Do not pull to the end of the rope: this can damage the starter. Hold onto the grip during rewinding.

Pull the starter rope until the first firing of the engine is heard (no more than five pulls).

NOTE: A new unit may require additional pulls.

9.Push choke lever to half choke position (J).

10.Pull starter until engine runs.

NOTE: Allow the saw to run in this position 15-30 seconds depending upon the temperature.

11.Push choke lever all the way IN (K).

12.SQUEEZE and release the throttle trigger.

Depress the throttle trigger which releases the trigger lock button. Squeeze and release the throttle trigger to let the engine idle.

13.Move chain brake to RUN position.

Place chain brake lever/hand guard into the RUN position. Refer to “Operation – Operating the Chain Brake” later in this manual for additional information.

CAUTION:

Failure to release partial throttle when chain brake lever is in the brake position will result in serious damage to the unit. Never squeeze and hold the throttle trigger while the chain brake is in the brake position.

Now you are ready to pick up the saw. Use the proper grip for both handles, refer to “Operation – Proper Grip on Handles” later in this manual for additional information.

STARTING A WARM ENGINE:

Follow the instructions for starting a cold engine (steps 1-9), but do not attempt to start in the full choke position (skip step 5). Push and release primer bulb 7 times. Pull the choke out and push back it in to the original run position.

STOPPING THE ENGINE

See Figure 15.

Release the throttle trigger and let the engine return to idle. To stop the engine, move the ignition switch to the “O” stop position (L). Do not put the chainsaw on the ground when the chain is still moving. For additional safety, set the chain brake when the saw is not in use.

In the event that the ignition switch will not stop the saw, pull the choke lever out to the fully extended position (Full Choke / ) and engage chain brake to stop the engine.

If the ignition switch will not stop the saw when set to the “O” stop position, have the ignition switch repaired before using the chainsaw again to prevent unsafe conditions or serious injury.

Important: When you finish using the saw, relieve tank pressures by loosening the CHAIN OIL and FUEL MIX caps. Then retighten the caps. Allow the engine to cool before storing.

PREPARING FOR CUTTING

PROPER CLOTHING FOR SAFETY
