MAINTAINING YOUR EDGER-TRIMMER
To minimize the chance of injury, perform all
maintenance and adjustments on your edger-
trimmer with engine o, unless instructed
otherwise in this section. Use extreme care
when working near operating machinery.
Do not wear loose tting clothing. Remove
watch and jewelry before beginning work
and observe common safety practices when
using tools.
CAUTION
MAINTENANCE CHECKLIST
1. Refer to the engine manual for engine main-
tenance instructions.
2. Correct grade of oil and gasoline is included
in the instructions.
Check the oil level of the engine every time the
edger-trimmer is used. An improper oil level can
cause extensive internal damage to engine.
Failure to change engine oil at recommended
intervals can lead to serious damage to engine.
This is especially true when using detergent
oils which are designed to hold impurities in
suspension; when saturation point is reached,
oil may suddenly break down to form a gelatin-
like substance which seriously impairs and can
even stop ow of oil. Increase frequency of oil
changes if edger-trimmer is operated under
extremely dusty conditions.
SPARK PLUG
Engine misre, or generally poor operation, is
often caused by spark plug in poor condition or
with incorrect spark gap setting. Spark plug should
be checked after each fty hours of operation.
Replace a spark plug at one hundred operating
hour intervals, or sooner if inspection reveals
fouling or excessive deterioration.
Always clean area around spark plug before
removing it to prevent dirt from entering engine.
Use a spark wrench to remove and install plug.
Check condition of plug. Good operating
conditions are indicated by a light coating of grey
or tan deposit. A dead white, blistered coating
could indicate an "overrich" fuel mixture caused
by a clogged air cleaner, or improper carburetor
adjustment.
Replace spark plug that is not in
good condition.
Never sand blast, wire brush, scrape, or reinstall
spark plug in poor condition. Best results are
obtained with a new plug.
Always check spark plug gap before installing a
new plug or reinstalling the original plug. Use a
spark plug gap gauge to adjust the electrode air
gap as indicated in the engine manual.
BLADE MAINTENANCE
Sharp edges of edger-trimmer blade can cut
you during blade maintenance or adjust-
ment. Use suitable covering over cutting
edges of blade to prevent bodily harm.
CAUTION
BLADE CHANGE
1. Place a 5/16" Allen wrench on the inside of
cutterhead shaft and a 3/4" wrench on the
blade nut, and turn to loosen nut. Remove
outer washer and old blade.
2. Replace blade with only Husqvarna blade
(available in 3-pack). Place outer washer the
same direction as removed, and tighten nut
as snug as possible.
LUBRICATION (See Fig. 5)
1. The cutterhead body needs occasional greas-
ing. Use #2 multi-purpose grease.
2. The cutterhead mandrel has two precision-
sealed bearings that do not need lubrication.
USE #2 MULTI-PURPOSE GREASE
Oil all exposed bearings, linkage, and front
wheels. Check all nuts and bolts for tightness.
