Installing or removing dust cover attachment 
(Optional accessory) 

WARNING: 

• 

Always be sure that the tool is switched off and 
unplugged before installing or removing the 
dust cover attachment.

 Failure to do so causes 

damage to the tool or a personal injury. 

There are four pieces of dust cover attachment and each 
is used in one of different positions. 

Fig.17 

Set the dust cover attachment so that the marking (A, B, 
C or D) places as shown. Snap its pins in the vents. 
Dust cover attachment can be removed by hand. 

NOTE: 

• 

Clean out the dust cover attachment when it is 
clogged with dust or foreign matters. Continuing 
operation with a clogged dust cover attachment will 
damage the tool. 

OPERATION 

WARNING: 

• 

It should never be necessary to force the tool. The 
weight of the tool applies adequate pressure. 
Forcing and excessive pressure could cause 
dangerous wheel breakage. 

• 

ALWAYS replace wheel if tool is dropped while 
grinding. 

• 

NEVER bang or hit grinding disc or wheel onto 
work. 

• 

Avoid bouncing and snagging the wheel, especially 
when working corners, sharp edges etc. This can 
cause loss of control and kickback. 

• 

NEVER use tool with wood cutting blades and 
other saw blades. Such blades when used on a 
grinder frequently kick and cause loss of control 
leading to personal injury. 

CAUTION: 

• 

Never switch on the tool when it is in contact with 
the workpiece, it may cause an injury to operator. 

• 

Always wear safety goggles or a face shield during 
operation. 

• 

After operation, always switch off the tool and wait 
until the wheel has come to a complete stop before 
putting the tool down. 

Grinding and sanding operation 

Fig.18 

ALWAYS hold the tool firmly with one hand on housing 
and the other on the side handle. Turn the tool on and 
then apply the wheel or disc to the workpiece. 
In general, keep the edge of the wheel or disc at an 
angle of about 15

ﾟ

  to the workpiece surface. 

During the break-in period with a new wheel, do not work 
the grinder in the B direction or it will cut into the 
workpiece. Once the edge of the wheel has been 
rounded off by use, the wheel may be worked in both A 
and B direction.
