1. Saw blade
2. Screw
3. Grinding wheel
4. Wing nut A
5. Holder A

Loosen the wing nut B and slide the holder B so that the 
“gullet” or slot between the saw blade Teeth just comes in 
contact with the edge of the Wheel. Slide the stopper so 
that it comes in contact with the holder B and tighten the 
wing nut B securely.

 WARNING:

Always disconnect the bench grinder from the power 
source before performing any assembly or adjustment.

Failure to do so could result in accidental starting resulting 
in possible serious personal injury.

WHEEL REPLACEMENT

See Fig.13.
If you must replace a grinding wheel, be sure to obtain 
one with a safe rated speed at least as high as the “no 
load speed” RPM marked on the data plate of the grinder 
and which is marked to comply with EN12413.

To replace the grinding wheel, remove the wheel cover by 
loosening the screws with holding the nut wrench.
Loosen the wheel nut in a clockwise direction for the left 
side and a counterclockwise direction for the right side 
using the correct wrench. Remove the outer flange and 
grinding wheel. To install a new grinding wheel, reverse 
the above procedure.
Be sure the grinding wheel and outer flange are properly 
seated on the spindle shaft.

 WARNING:

When servicing, use only manufacturers recommended 
replacement parts. Use of other part may create a hazard 
and cause product damage.

GENERAL

Keep the bench grinder clean. Remove dust from working 
parts and beneath the grinder frequently.
Make sure the bench grinder operates properly. Check 
screws, nuts, and bolts for tightness.

EXTENSION CORDS

The use of any extension cord will cause some loss of 
power. To keep the loss to a minimum and to prevent tool 
overheating, use an extension cord that is heavy enough 
to carry the current the tool will draw.
An extension lead of cross sectional area of at least 
1.5 mm

2

 is recommended for an extension cord 8 meters 

or less in length. When working outdoors, use an 
extension cord that is suitable for outdoor use.

 WARNING:

Check extension cords before each use. If damaged, 
replace immediately. Never use tool with damaged cord 
since touching the damaged area could cause electrical 
shock resulting in serious injury.

WORKLIGHT BULB REPLACEMENT

1. Light bulb

When the light bulb is worn out and no longer working, 
unfasten the screws which fix the lamp cover, then gently 
remove the bulb from the holder by pushing in and turning 
anticlockwise. Contact your dealer for replacement part. 
To replace, gently push the light bulb into the insert and 
turn clockwise, then fix the lamp cover in the revise order.

WHEEL DRESSING TOOL (Accessory)

Dressing a wheel is done to renew sharpness or to true up 
the face of the wheel.
Set the work rest of the bench grinder at a slight angle 
and brace the wheel-dressing tool against it. Do not make 
contact with the grinding wheel until after you have turned 
on the motor and the wheel is rotating at full speed. Press 
the dressing tool slightly against the rotating wheel until 
you get a bite, then move slowly from side to side across 
the wheel. A small bite and many passes are better than a 
big bite and one pass. Work cautiously; hold the dresser 
with force on the work rest. Do not use excessive 
pressure against the grinding wheel. Proceed slowly until 
you master the technique.
