PRIOR TO OPERATION

1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specified on the product
nameplate.
2. Power switch
Ensure that the power switch is in the OFF position. If
the plug is connected to a receptacle while the power
switch is in the ON position, the power tool will start
operating immediately, which could cause a serious
accident.
3. Extension cord
When the work area is removed from the power
source, use an extension cord of sufficient thickness
and rated capacity. The extension cord should be
kept as short as practicable.
4. Installing a wheel
Install the wheel so that length
If
is longer, abnormal vibration will occur, and the
machine is not only negatively affected, but there is a
possibility of a serious accident.
Make the
as small as possible.
When d = 6 mm, 6.35 mm (1/4"), 8 mm, D of the
wheel should be less than 25 mm. If a wheel with D
more than 25 mm is used, the circumference speed
exceeds the safety limit and the wheel will break.
Never use such a wheel.
Distance L varies for D. Determine L referring to the
table below.
When d = 3 mm, 3.175 mm (1/8"), D should be less
than 10 mm. Determine L referring to the table below.
Wheels can be simply attached and detached by
using the two wrenches (Fig. 2).
NOTE
Do not tighten the collet chuck by inserting a shaft
thinner than the regular shaft diameter (6 mm) in the
chuck or in an empty condition. This practice will
damage the collet chuck.
When installing a wheel with shaft, tighten the collet
chuck after applying a small quantity of spindle oil
(or sewing machine oil) to the tapered portion
indicated in Fig. 1.
