Is Your Trimmer Ready To Go; Safety Inspection; Cutting Attachment Inspection; Maintenance - Honda UMK431 Owner's Manual

BEFORE OPERATION
IS YOUR TRIMMER READY TO GO?
For your safety, and to maximize the service life
of your equipment, it is very important to take a
few moments before you operate the trimmer to
check its condition. Be sure to take care of any
problem you find, or have your servicing dealer
correct it, before you operate the trimmer.
Improperly maintaining this trimmer, or
failing to correct a problem before
operation, could cause a malfunction in
which you could be seriously injured.
Always perform a preoperation inspection
before each operation, and correct any
problem.
Safety Inspection
Look around the engine for signs of oil or
gasoline leaks. Wipe up any spills before
starting the engine.
Replace any damaged parts.
Check that all fasteners are in place and
secure. Tighten as necessary.
Cutting Attachment Inspection
Look for signs of damage to the cutting
attachment (see pages 33 and 39). Replace
any cutting attachment and parts that are worn
out, bent, cracked, chipped, or damaged in any
way.
If using a metal blade, be sure it is sharp. A
dull blade is more likely to snag and thrust.
If using a metal blade on a trimmer equipped
with a loop handle, be sure the barrier bar
(optional part) is installed beneath the loop
handle.
Make sure the cutting attachment is properly
installed and securely fastened (see pages 38
and 40).
Check that the debris shield is the correct
shield for the cutting attachment (see page
9),
and that it is securely installed and in good
condition.
Maintenance Inspection
Check the oil level (see page 26). Running the
engine with a low oil level can cause engine
damage.
Check the air filter (see page 27). A dirty air
filter will restrict air flow to the carburetor,
reducing engine and trimmer performance.
Check throttle cable free play (see page 30).
The cable must be correctly adjusted and
operate smoothly for good throttle control.
Check the fuel level (see page 31). Starting
with a full tank will help to eliminate or reduce
operating interruptions for refueling.
