BLADE SHARPENING

■

The product performs at its best by following 

these steps. Before use, always check 

that the blades are not in contact with the 

shaving plate. For optimal performance, 

keep a 1 mm gap between the blades and 

the shaving plate.

■

If the product fails to shred material, the 

blades may need to be sharpened.

■

Over time, the blades on the product 

need to be sharpened. This can be 

completed by adjusting the shaving plate 

so that it will come into light contact with 

the blades. Ensure that the product is 

turned on and working in normal forward 

direction. Adjusting the shaving plate 

while the motor is turned off could 

lead to serious damage to the product. 

NOTE:

 Adjusting the shaving plate should 

only be attempted when deemed totally 

necessary. Adjusting the shaving plate too 

often or too far could cause the product to 

stop working.

■

While the product is running, turn the 

adjusting knob clockwise.

■

When you hear metal on metal contact 

or you see fine aluminum shavings in the 

bottom of the collection container, stop 

the adjustment and allow the product 

to run for 30 seconds to sharpen the 

blades. Once sharpening is complete, turn 

the adjustment knob counterclockwise 

until it is no longer in contact with the 

shaving plate, leaving a 1 mm gap. 

NOTE:

 Sharpening the blades requires 

very light contact with the shaving plate. 

Complete any adjustment slowly to avoid 

damaging the product. Overadjusting the 

plate can cause serious damage to the 

product.

RESIDUAL RISK

Even when the product is used as prescribed, 

it is still impossible to completely eliminate 

certain residual risk factors. The following 

hazards may arise during use and the 

operator should pay special attention to avoid 

the following:

■

injury caused by exposure to noise

–

Wear hearing protection and limit 

exposure.

■

injury caused by inhalation of dust and 

particles

–

Wear dust mask with filter when 

necessary.

■

injury caused by contact with the cutting 

mechanism

–

Keep unprotected body parts away from 

the cutting mechanism at all times.

RISK REDUCTION

It has been reported that vibrations from 

handheld tools may contribute to a condition 

called Raynaud’s Syndrome. Symptoms may 

include tingling, numbness, and blanching of 

the fingers, usually apparent  upon exposure 

to cold. Hereditary factors, exposure to cold 

and dampness, diet, smoking, and work 

practices are all thought to contribute to the 

development of these symptoms. There are 

measures that can be taken bythe operator to 

possibly reduce the effects of vibration:

■

Keep your body warm in cold weather. 

When operating the product, wear gloves 

to keep the hands and wrists warm. It is 

reported that cold weather is a major factor 

contributing to Raynaud’s Syndrome.

■

After each period of operation, exercise to 

increase blood circulation.

■

Take frequent work breaks. Limit the 

amount of exposure per day.

If you experience any of the symptoms of this 

condition, immediately discontinue use and 

see your physician.

 WARNING

Injuries may be caused, or aggravated, by 

prolonged use of a tool. When using any 

tool for prolonged periods, ensure you take 

regular breaks.
