Maintenance and care
The cutter blades are very sharp. Always wear gloves
when working around the cutter assembly.
Failure to observe the precautions could cause an accident
or injury, or even lead to a fatality.
Cutting performance of your machine depends a great deal on
proper cutter blade adjustment. Properly adjusted blades will os-
cillate freely yet help prevent binding of cut material between
blades. Adjust blades as follows:
1. Loosen all blade locknuts at least one full turn.
2. Tighten each blade shoulder bolt firmly, and then loosen the
shoulder bolts 1/4 to 1/2 turn.
3. Working from the gearcase end, lock each bolt in place by
firmly tightening its locknut while preventing the shoulder
bolt from turning.
When shoulder bolt adjustment is correct, there should be a gap
of 0.25–0.50 mm between the cutter blades and the flat washers,
and the flat washer beneath each bolt head should turn freely.
Operating the trimmer with worn or improperly adjusted
cutters will reduce cutter performance and may also
damage your machine. Never operate the machine with
damaged or worn cutters.
Prior to each work day, perform the following:
Remove all dirt and debris from the engine, check the cooling
fins and air cleaner for clogging, and clean as necessary.
Carefully remove any accumulations of dirt or debris from the
silencer and fuel tank. Check cooling air intake area at base of
crankcase. Remove all debris. Dirt build-up in these areas can
lead to engine overheating, fire, or premature wear.
Lubricate the blade before use and after refueling. Check the
cutter for damage or incorrect adjustment.
Always wear gloves when working around the cutter as-
sembly.
Failure to observe the precautions could cause an accident
or injury, or even lead to a fatality.
Clean any debris or dirt from the cutting attachment.
Check for loose or missing screws or components. Make sure
the cutter attachment is securely fastened.
Check the entire unit for leaking fuel or grease.
Make sure nuts, bolts, and screws (except carburetor idle
speed adjusting screws) are tight.
