WARNING: Refer to section Recommended Oil Type and follow all warnings and safety instructions in the operator’s manual. Failure to do so can result in serious injury to the operator and/or bystanders.
ADDING OIL TO CRANKCASE – INITIAL USE
NOTE: This unit is shipped without oil in the crankcase. In order to avoid damage to the unit, put oil in the crankcase before attempting to start unit.
Your unit is supplied with one 100 ml (3.4 fl oz.) bottle of SAE 30 SF, SG, SH oil.
For cold weather operation, temperatures below 4º C (40°F) use a
Follow the instructions in your Operator's Manual for adding the correct amount of oil to this unit.
HOLDING THE TRIMMER
Before operating the unit, stand in the operating position (Fig. 23). Check for the following:
•The operator is wearing eye protection and proper clothing.
•Harness is adjusted to proper position.
•The handlebar is adjusted so the hands grip it without
•The unit is below waist level.
•The cutting attachment is parallel to the ground and easily contacts the vegetation to be cut without the operator having to bend over.
ADJUSTING TRIMMING LINE LENGTH
The Bump Head cutting attachment allows you to release trimming line without stopping the engine. To release more line, lightly tap the cutting attachment on the ground (Fig. 24) while operating the trimmer at high speed.
NOTE: Always keep the trimming line fully extended. Line release becomes more difficult as cutting line becomes shorter.
Each time the head is bumped, about 25.4 mm (1 in.) of trimming line is released. A blade in the cutting attachment guard will cut the line to the proper length if excess line is released. For best results, tap the Bump Head on bare ground or hard soil. If line release is attempted in tall grass, the engine may stall. Always keep the trimming line fully extended. Line release becomes more difficult as the cutting line becomes shorter.
NOTE: Do not rest the Bump Head on the ground.
Some line breakage will occur from:
•Entanglement with foreign matter
•Normal line fatigue
•Attempting to cut thick, stalky weeds
•Forcing the line into objects like walls or fence posts
TIPS FOR BEST TRIMMING RESULTS
•Keep the cutting attachment parallel to the ground.
•Do not force the cutting attachment. Allow the tip of the line to do the cutting, especially along walls. Cutting with more than the tip will reduce cutting efficiency and may overload the engine.
•Cut grass over 200 mm (8 in.) by working from top to bottom in small increments to avoid premature line wear or engine drag.
•Cut from left to right whenever possible. Cutting to the right improves the unit's cutting efficiency. Clippings are thrown away from the operator.
•Slowly move the trimmer into and out of the cutting area at the desired height. Move either in a forward- backward or
