WARNING
CURB RIDING POSITION
Remove the spacer from between the front
wheels. Slide the right wheel toward the left wheel
and replace the spacer between the wheel and
right frame. Only vertical edging can be done in
this position.
WHEEL POSITIONING (See Fig. 4)
The wheel adjusting spacer should be centered
between the wheels when edging in the vertical
position. Wheels must be in the dual position
to the right when edging with cutterhead in an
angle position or trimming (horizontal position).
Remove the spacer from between the wheels
by lifting on spacer with open side down. Slide
the left front wheel on the axle toward the
right wheel, and once again install the spacer
on the axle between the frame and wheel.
NOTE: As pictured above, wheels are positioned

CORRECT EDGER-TRIMMER USAGE
Readallmanualsprovidedbeforeoperating.
These manuals give a detailed description
of operation and point out other areas of
caution. Familiarize yourself thoroughly
with equipment before attempting to use it.
CAUTION
OPERATION OF THE EDGER-
TRIMMER
Keep all shields in place. Never at-
tempt to clear discharge areas or edger-
trimmer blade wihout disengaging the
edger-trimmer and stopping the engine.
WARNING
Your edger-trimmer is designed to give a
professionally groomed appearance to your
lawn with minimum eort. It will edge lawns at
walks, around ower beds, trim close to poles
and hydrants, and also under fences and other
hard to reach locations. For best appearance
around owers, adjust blade to 20" angle cut.
For best results, adjust the cutting depth of the
blade to within 1/2" to 1" deep (with a new blade
usually in the third notch of the adjustment bracket
at handle).
Too deep a cut will put unnecessary stress
on engine and accelerate blade wear. Cutting
too shallow allows rapid regrowth of roots.
Make sure to re-adjust cutting depth as blade
begins to wear at tips.
Avoid edging or trimming in wet grass, as it may
clog up in the blade guard and cause splattering.
The general appearance will be much better when
grass is dry.
Always push edger-trimmer at moderate walking
speed — at this speed your edger-trimmer is
designed to cut more than 100 ft. per minute.
Four-wheel design of edger-trimmer permits easy
and stable edging, riding securely on sidewalk or
cement surfaces.
Around specially shaped ower beds or curved
sections, follow these simple steps. It will be
easier to cut around corners when front wheels
are placed together at right side of trimmer-edger.
Before starting engine, remove wheel spacer
clip on front axle, slide wheels to side away from
blade, and replace spacer.
After starting engine, set blade depth and by
slightly lifting rear wheels, guide edger-trimmer
around corners and odd angles.

MAINTAINING YOUR EDGER-TRIMMER
To minimize the chanceofinjury,performall
maintenanceandadjustmentsonyouredger-
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
andobservecommonsafetypracticeswhen
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 misre, 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
Sharpedgesof edger-trimmerbladecan 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. Thecutterheadbodyneedsoccasionalgreas-
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.
