ikc WARNING \
This unit is equipped with an internal combustion engine and should not be used on or near any unim proved forest-covered, brush-covered or grass-covered land unless the engine's exhaust system is equipped with a spark arrester meeting applicable local 5r state laws (if any). If a spark arrester is used, it should be maintained in effective working order by the operator.
In the State of California the above is required by law (Section 4442 of the California Public Resources Code). Other states may have similar laws. Federal laws apply on federal lands. A spark arrester muffler is available at your nearest engine authorized serv ce center.

SAFE OPERATION PRACTICES FOR EDGERS

TRAINING
1. Read this owner's manual carefully in its en tirety before attempting to assemble or operate this machine. Be completely familiar with the controls and the proper use of this machine be fore operating it. Keep this manual in a safe place for future and regular reference and for ordering replacement parts.
2. Your edger is a precision piece of power equip ment, not a plaything. Therefore, exercise extreme caution at all times.
3. Never allow children to operate a power edger. Only persons well acquainted with these rules of safe operation should be allowed to use your edger.
4. Keep the area of operation clear of all persons,
particularly small children and pets. Stop engine when they are in the vicinity of your edger. Al though the area of operation should be complete
ly cleared of foreign objects, an object may have
been overlooked and could be accidently thrown
by the edger in any direction and cause serious
personal injury to the operator or any others
allowed in the area.
. No one should operate this unit while intoxicated
or while taking medication that impairs the senses
or reactions.
PREPARATION
1. Thoroughly inspect the area where the equip ment is to be used. Remove all stones, sticks, wire, bones and other foreign objects which could be picked up and thrown by the edger in any direction and cause serious personal injury to the operator or any others allowed in the area.
2. Do not operate equipment when barefoot or wear ing open sandals. Always wear substantial foot wear.
3. Check the fuel before starting the engine. Gasoline is an extremely flammable fuel. Do not fill the gasoline tank indoors, while the engine is running, or while the engine is still hot. Wipe off any spilled gasoline before starting the engine as it may cause a fire or explosion.
4. Disengage the blade clutch on units so equipped before starting the engine.
Never attempt to make a wheel adjustment while
the engine is running.
d. Never operate the equipment in wet grass. Always
be sure of your footing. A slip and fall can cause serious personal injury. Keep a firm hold on the handle and walk, never run.
OPERATION
1. Never operate this edger unless wearing safety glasses or some other suitable eye protection at all times the engine is running.
2. Do not change the engine governor settings or overspeed the engine.
3. Do not put hands or feet near or under rotating parts. Keep clear of the discharge opening at all times as the rotating blade can cause injury.
4. Stop the blade when crossing gravel drives, walks or roads.
5. After striking a foreign object, stop the engine, remove the wire from the spark plug, and thor oughly inspect the edger for any damage. Repair the damage before restarting and operating the edger.
6. If the equipment should start to vibrate abnor mally, stop the engine and check immediately for the cause. Vibration is generally a warning of trouble.
7. Stop the engine whenever you leave the equip ment, before cleaning the guard assembly, and when making any repairs or inspections.
8. Before cleaning, repairing or inspecting, make certain the blade and all moving parts have stop ped. Disconnect the spark plug wire, and keep
the wire away from the spark plug to prevent accidental starting.
9. Do not run the engine indoors.
10. Shut the engine off and wait until the blade
comes to a complete stop before unclogging guard assembly.
11. Never operate edger without proper guards, plates
or other safety protective devices in place.
12. Always operate the edger so that the protective
guard guide is positioned between the walk and the rotating blade. Never allow the rotating blade to operate directly against concrete walk or drive.
MAINTENANCE AND STORAGE
1. Check the blade and engine mounting bolts at frequent intervals for proper tightness.
2. Keep all nuts, bolts, and screws tight to be sure the equipment is in safe working condition.
3. Never store the equipment with gasoline in the tank inside of a building where fumes may reach an open flame or spark. Allow the engine to cool before storing in any enclosure.
4. To reduce fire hazard, keep the engine free of grass, leaves, or excessive grease.

CONTROLS

THROTTLE CONTROL The throttle control lever is located on the handle
panel. It regulates the engine speed and stops the engine. See figure 12.
18.
Pull the blade and guard assembly all the way back by hand until there is slack in the belt. See figure
11.
Secure the end of the lower clutch rod half to the
19.
arm extension on the pivot bracket with cotter pin
(C). See figure 11.
20.
Secure the throttle control cable to handles with two cable ties (I).
DEPTH CONTROL ADJUSTMENT
The engagement handle controls the clutching and
declutching of the belt. To declutch, the handle is pulled back toward the operator. The farther forward
the handle is pushed, the deeper the cut. To move the
engagement handle, first move it to the left so the the handle is out of the notch. See figure 12.
NOTE
If belt slips when engagement handle
is in the engaged position, lengthen the clutch rod by turning the rod adjust ment link. Refer to figure 10.
FIG U RE 1 2
Page 8
BLADE PLANE ADJUSTMENT
The cutting blade can be adjusted to eight positic>ns from vertical to horizontal. To adjust, release tie adjustment lever on the pivot bracket and rotate lhe spindle housing. Place adjustment lever in notch desired. See figure 13.
When the blade is adjusted toward the horizontal position, the front wheels must also be adjusted.
Remove the two hairpin cotters and slide the spacer and wheel to the right as shown in figure 14. Reinse.'rt the hairpin cotters.
NOTE
If the wheels are not adjusted, the blade will hit the left front wheel, causing the belt to slip.
Become familiar with all the controls and adjustments before operating the edger so you can adjust it easily to a variety of cutting and trimming conditions. While
the engine is running, DO NOT ATTEMPT TO MAKE ANY ADJUSTMENTS except with the throttle control.
