4 - FUEL AND LUBRICATION

4-1. FUEL

Use regular grade unleaded gasoline mixed with Genuine

McCulloch 40:1 2-cycle engine oil for best results. Use mix-

ing ratios in Section 4-3.

Never use straight gasoline in your unit. This will cause

permanent engine damage and void the manufactur-

er’s warranty for that product. Never use a fuel mixture that

has been stored for over 90 days.

If 2-cycle lubricant other than Genuine McCulloch

Custom Lubricant is to be used, it must be a premium

grade oil for 2-cycle air cooled engines mixed at a 40:1

ratio. Do not use any 2-cycle oil product with a recommend-

ed mixing ratio of 100:1. If insufficient lubrication is the

cause of engine damage, it voids the manufacturer’s

engine warranty for that occurrence.

4-2. MIXING FUEL

Mix fuel with Genuine McCulloch brand 2 cycle oil in an

approved container. Use mixing table for correct ratio of fuel

to oil. Shake container to ensure thorough mix.

Lack of lubrication voids engine warranty.

5 - STARTING/STOPPING INSTRUCTIONS

5-1. STARTING A COLD ENGINE

Fill fuel tank with proper gas and oil mixture. See FUEL

AND LUBRICATION. Set unit upright on ground so that it

rests on the back pack frame.

1. Pump primer bulb10 X by pressing up on the bulb (D).

(Fig. 5-1B)

2. Your unit is designed with a 3 position choke: FULL

CHOKE “ ”, PARTIAL CHOKE “ ”, and RUN “ ”.

Move choke lever to FULL CHOKE “ ” position. (Fig.

5-1A)

3. Set throttle lock (C): While holding trigger (B) at wide

open position, press down and hold throttle lock (C).

Release throttle trigger (B), then release throttle lock

(C). Throttle trigger (B) will now remain in the wide

open position. Make sure ignition switch is in the ON

(I) position. (Fig. 5-1C)

NOTE: Easy Start power assist starting significantly

reduces the pulling effort. Pull the starter cord slowly to

about 3 1/2 feet, the power assist will turn over the engine

with little resistence from the engine.

4. With the unit on the ground, hold the top assist handle

and step on the bottom of the frame with foot. (Fig. 5-

1D)

5. Pull starter rope 4-6 times-if unit does not start move

choke lever to “ ” position and pull 4-6 more times

(Fig. 5-1E). Wait 10 sec. after unit starts then move

choke lever to “ ” position. (Fig. 5-1F)

6. Press trigger to run.

NOTE: If engine fails to start after repeated attempts, refer

to Troubleshooting section.

NOTE: Always pull starter rope straight out. Pulling starter

at an angle will cause rope to rub against the eyelet. This

friction will cause the rope to fray and wear more quickly.

Always hold starter handle when rope retracts. Never allow

rope to snap back from extended position. This could cause

rope to snag or fray and also damage the starter assembly.
