to unsafe conditions. DO NOT operate unit if any wires (power,  
telephone, cable, etc.) are closer than 4.5 M (15 ft.) to any part of the  
operator or unit.  
• Spectators and fellow workers must be warned, and children and  
animals prevented from coming nearer than 15 M (50 ft.) while the  
Hedge Clipper is in use.  
Operation

Operation (HCA)  
• Never adjust blade angle of HCA while standing.  
• Only adjust cutting angle with HCA resting flat on the ground, with  
the engine stop switch in the "STOP" position.  
• Adjust cutting angle by moving locking lever (A) up. Depress blade  
indexing lever (B) and change blade angle with rear cutter assembly  
handle. Release indexing lever (B) into notch. Move locking lever (A)  
down to completely engage internal gears.

C
IMPORTANT  
B
Lever (A) does not secure gearbox angle setting. Moving lever in  
the down position reduces internal play in the gear box. Do not  
over tighten castle nut (C) to insure gear box angle setting  
tightness because damage to internal gears will occur. If the lever  
is loose or very tight adjust nut (C) for snug 90° movement.

EXTENDED OPERATION/EXTREME CONDITIONS  
Vibration and Cold  
It is believed that a condition called Raynaud’s Phenomenon, which  
affects the fingers of certain individuals may be brought about by  
exposure to vibration and cold. Exposure to vibration and cold may  
cause tingling and burning sensations followed by loss of color and  
numbness in the fingers. The following precautions are strongly  
recommended because the minimum exposure which might trigger the  
ailment is unknown.  
• Keep your body warm, especially the head, neck, feet, ankles,  
hands and wrists.  
• Maintain good blood circulation by performing vigorous arm  
exercises during frequent work breaks and also by not smoking.  
• Limit the hours of operation. Try to fill each day with jobs where  
operating the trimmer or other hand-held power equipment is not  
required.  
• If you experience discomfort, redness and swelling of the fingers  
followed by whitening and loss of feeling, consult your physician  
before further exposing yourself to cold and vibration.  
Repetitive Stress Injuries  
It is believed that overusing the muscles and tendons of the fingers,  
hands, arms and shoulders may cause soreness, swelling, numbness,  
weakness and extreme pain in those areas. Certain repetitive hand  
activities may put you at a high risk for developing a Repetitive Stress  
Injury(RSI). AnextremeRSIconditionisCarpalTunnelSyndrome  
(CTS), which could occur when your wrist swells and squeezes a vital  
nerve that runs through the area. Some believe that prolonged exposure  
to vibration may contribute to CTS. CTS can cause severe pain for  
months or even years.  
To reduce the risk of RSI/CTS, do the following:  
• Avoid using your wrist in a bent, extended or twisted position.  
Instead try to maintain a straight wrist position. Also, when grasping,  
use your whole hand, not just the thumb and index finger.  
• Take periodic breaks to minimize repetition and rest your hands.  
• Reduce the speed and force with which you do the repetitive  
movement.  
• Do exercises to strengthen the hand and arm muscles.  
• Immediately stop using all power equipment and consult a doctor if  
you feel tingling, numbness or pain in the fingers, hands, wrists or  
arms. The sooner RSI/CTS is diagnosed, the more likely permanent  
nerve and muscle damage can be prevented.

• Fuel tanks/cans may be under pressure. Always loosen fuel caps  
slowly allowing pressure to equalize.  
• NEVER refuel a unit when the engine is HOT!  
• NEVER refuel a unit with the engine running.  
• DO NOT fill fuel tanks indoors. ALWAYS fill fuel tanks outdoors  
over bare ground.  
• Securely tighten fuel cap after refueling.  
• Inspect for fuel leakage. If fuel leak is found, do not start or operate  
unit until leak is repaired.  
After Refueling;  
• Wipe any spilled fuel from the unit.  
3M (10 ft.)  
• Move at least 3M (10 ft.) from refueling location before starting.  
After Use;  
• DO NOT store a unit with fuel in its tank. Leaks can occur. Return  
unused fuel to an approved fuel storage container.  
Storage  
Fuel storage laws vary by locality. Contact your local government for  
the laws affecting your area. As a precaution, store fuel in an approved,  
air tight container. Store in a well ventilated, unoccupied building, away  
from sparks and flames. Do not store fuel longer than 30 days.

thirty (30) days, ninety (90) days when a fuel stabilizer is added.  
IMPORTANT  
Stored two-stroke fuel may separate. ALWAYS shake fuel con-  
tainer thoroughly before each use.  
EQUIPMENT CHECK  
Before operation a complete check of the unit must be performed;  
• Check unit for loose/missing nuts, bolts and screws. Tighten and/or  
replace as needed.  
• Inspect fuel lines, tank and area around carburetor for fuel leaks.  
DO NOT operate unit if leaks are found.  
• Inspect hand guard for damage. Replace if damaged or missing.  
• Check that the blade assembly is firmly attached and in safe operating  
condition. Dull, loose or damaged blades should not be used.  
• Tighten the Blade angle adjustment lever before operating the  
HCA-2400.  
• Check that front (loop) handle and shoulder strap/ or shoulder/waist  
harness are adjusted for safe, comfortable operation.  
IMPORTANT  
Always store and transport Shaft Hedge Clipper in a stable,  
horizontal position. Support gear case and cutting blades to prevent  
excessive flexing, which may cause damage to the cutting attach-  
ment.

DETERMINE OPERATION AREA  
WARNING  
DANGER  
Inspect starting area for hazards such as rocks, glass, debris etc.  
which could be contacted by the cutting blades when starting. Keep  
helpers and bystanders at least 15 M (50 ft.) from starting area,  
otherwise serious personal injury may result.  
• Review the area to be trimmed. Look for hazards that could contribute  
to unsafe conditions.  
• Spectators and fellow workers must be warned, and children and  
animals prevented from coming nearer than 15 M (50 ft.) while the  
trimmerisinuse.  
OPERATION  
15 M  
(50FT.)  
• Provide all operators of this equipment with the operator's manual and  
instructions for safe operation.  
• Before starting the unit, equip yourself and any other person working  
within the 15 M (50 ft.) Safety Zone with the required Protective  
Equipment and clothing.  
• Check that front (loop) handle and shoulder strap/ or shoulder/  
waist harness are adjusted for safe, comfortable operation.  
15 M  
(50 FT.)  
• During operation, the complete unit, especially the gear box, drive  
shaft housing and power head muffler area may become very hot, too  
hot to touch. Avoid contact during and immediately after operation.

• Never adjust blade angle of HCA while standing  
• Only adjust cutting angle with HCA resting flat on the ground, with  
the engine stop switch in the "STOP" position.  
• Adjust cutting angle by moving locking lever (A) up. Depress blade  
indexing lever (B) and change blade angle with rear cutter assembly  
handle. Release indexing lever into notch. Move locking lever down  
to completely engage internal gears.  
IMPORTANT

C
Locking lever (A) does not secure gear box angle setting. Moving  
lever in the down position reduces internal play in the gear box.  
Do not over tighten castle nut (C) to insure gear box angle setting  
tightness because damage to internal gears will occur. If the lever  
is loose or very tight, adjust nut (C) for snug 90° movement.

COOLING SYSTEM CLEANING  
Level3.  
Tools required: Cross Head Screwdriver, 3 mm Hex wrench, 4 mm Hex  
wrench, Pointed Wood Stick, Cleaning Brush, 1"-2" medium bristle paint  
brush.  
Parts Required: None.  
IMPORTANT  
To maintain proper engine operating temperatures, cooling air must  
pass freely through the cylinder fin area. This flow of air carries  
combustion heat away from the engine.  
A
Overheating and engine seizure can occur when:  
Air intakes are blocked, preventing cooling air from reaching the  
cylinder.  
Dust and grass build up on the outside of the cylinder. This build  
up insulates the engine and prevents the heat from leaving.  
Removal of cooling passage blockages or cleaning of cooling fins is  
considered “Normal Maintenance”. Any failure attributed to lack of  
maintenance is not warranted.
