Makita BGA452 Grinder User Manual


 
12
Do not start the cutting operation in the workpiece.
Let the wheel reach full speed and carefully enter
into the cut moving the tool forward over the
workpiece surface. The wheel may bind, walk up
or kickback if the power tool is started in the
workpiece.
During cutting operations, never change the angle
of the wheel. Placing side pressure on the cut-off
wheel (as in grinding) will cause the wheel to crack
and break, causing serious personal injury.
A diamond wheel shall be operated perpendicular
to the material being cut.
MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and the
battery cartridge is removed before attempting to
perform inspection or maintenance.
Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may
result.
