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.

IMPORTANT

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). An extreme RSI condition is Carpal Tunnel Syndrome (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.
