4 - FUEL AND LUBRICATION

5 - OPERATING INSTRUCTIONS

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 5-3.

Never use straight gasoline in your unit. This will cause permanent engine damage and void the man- ufacturer’s warranty for that product. Never use a fuel mix-

ture that has been stored for over 90 days.

If 2-cycle lubricant other than Genuine McCulloch 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 recommended mix- ing ratio of 100:1. If insufficient lubrication is the cause of engine damage, it voids the manufacturer’s engine warran- ty.

4-2. MIXING FUEL

Add oil to an approved fuel container followed by the gaso- line to allow incoming gasoline to mix with oil. Shake con- tainer to ensure thorough mix.

Lack of lubrication voids engine warranty. Gasoline and oil must be mixed at 40:1.

4-4. RECOMMENDED FUELS

Some conventional gasolines are being blended with oxy- genates such as alcohol or an ether compound to meet clean air standards. Your McCulloch engine is designed to operate satisfactorily on any gasoline intended for automo- tive use including oxygenated gasolines.

5-1. STARTING A COLD ENGINE

NOTE: To minimize load on engine during starting and warm-up, trim excess cutting line to 5” (13cm) (Fig. 5-1A).

1.Move ignition switch to the “RUN (I)” position (Fig. 5- 1B).

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

“ ”, START “ ”, and RUN “ ”. Move choke lever to CHOKE “ ” position (Fig. 5-1C).

3.Prime the carburetor. Pump the primer bulb (A) 10 times (Fig. 5-1D).

4.Grip handle firmly – depress safety trigger (B) & throt- tle trigger (C) to the FULL THROTTLE position (Fig. 5- 1E).

5.Pull starter rope until resistance is felt (about 4”) (Fig. 5-1F). A smooth rapid pull is required for a strong spark. Pull starter rope briskly 4 times.

6.Move choke lever to START “ ” position (Fig. 5-1G).

7.Pull starter rope again 4 times while trigger is in the full throttle position.

8.Once engine starts, leave in the START “ ” position for 10 seconds.

9.Move the choke to RUN “ ” position (Fig. 5-1H).

10.If engine fails to start, repeat steps 1 through 9. NOTE: If engine fails to start after repeated attempts, refer to trouble shooting 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.
