Your risk from these exposures varies, depending on how often you do this type of work. To
reduce your exposure to these chemicals: work in a well ventilated area, and work with
approved safety equipment, such as those dust masks that are specially designed to
filter out microscopic particles.
• Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling,
and other construction activities. Wear protective clothing and wash exposed areas
with soap and water. Allowing dust to get into your mouth, eyes, or lay on the skin may pro -
mote absorption of harmful chemicals.
WARNING: Use of this tool can generate and/or disburse dust, which may cause serious
and permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory pro -
tection appropriate for the dust exposure. Direct particles away from face and body.
CAUTION: Use extra care when working into a corner because a sudden, sharp move -
ment of the cut-off tool may be experienced when the wheel or other accessory contacts a
secondary surface or a surface edge.
CAUTION: Wear appropriate personal hearing protection during use. Under some
conditions and duration of use, noise from this product may contribute to hearing loss.

ASSEMBLY
Attaching Side Handle (Fig. 1)
The side handle (E) can be fitted to either side of the gear case in the threaded holes, as
shown. Before using the tool, check that the handle is tightened securely.
OPERATION
Guards and Flanges
It is important to choose the correct guards and flanges to use with the cut-off tool accessories.
See Figure 2 for the correct accessories.
CAUTION: Accessories must be rated for at least the speed recommended on the tool
warning label. Wheels and other accessories running over rated accessory speed may fly
apart and cause injury. Every unthreaded accessory must have a 7/8" arbor hole. If it does not,
it may have been designed for a circular saw. Use only the accessories shown in Figure 2.
Accessory ratings must be above listed minimum wheel speed as shown on tool nameplate.
Mounting and Using Cutting Wheels (Type 1)
Cutting wheels include diamond wheels and abrasive discs. Abrasive cutting wheels for metal
and concrete use are available. Diamond cutting wheels for concrete cutting can also be used.
WARNING: A 4-1/2" closed, 2-sided cutting wheel guard is not included with this tool but is
required when using 4-1/2" cutting wheels. Failure to use proper flange and guard can result
in injury resulting from wheel breakage and wheel contact. See Figure 2 for more information.
MOUNTING GUARD (FIG. 3, 4)
CAUTION: Turn off and unplug the tool before making any adjustments or remov -
ing/installing attachments or accessories.
1 . Open the guard latch (J), and align the arrow (K) on the guard with the arrow (L) on the
hub. This will align the lugs with slots on the gear case cover. Position the guard facing
b a c k w a r d .
2 . Push the guard down until the guard lug engages and rotates freely in the groove on the
gear case hub.
3 . Rotate guard (I) into desired working position. The guard body should be positioned
between the spindle and the operator to provide maximum operator protection.
4 . Close the guard latch to secure the guard on the gear case cover. You should be unable
to rotate the guard by hand when the latch is in closed position. Do not operate grinder
with a loose guard or clamp lever in open position.
5 . To remove the guard, open the guard latch, rotate the guard so that the arrows are aligned
and pull up on the guard.
N O T E : The guard is pre-adjusted to the diameter of the gear case hub at the factory. If, after
a period of time, the guard becomes loose, tighten the adjusting screw (M) with the clamp lever
in the closed position (Fig. 5).
CAUTION: Do not tighten adjusting screw with clamp lever in open position. Undetectable
damage to guard or mounting hub may result.
MOUNTING CUTTING WHEELS
CAUTION: Turn off and unplug the tool before making any adjustments or removing
/installing attachments or accessories.
C A U T I O N : Matching diameter threaded backing flange and clamp nut (included with tool)
must be used.
1 . Place the anti-lockup backing flange on spindle with the pilot (N) facing up. Be sure the
backing flange recess is seated onto the flats of the spindle before placing wheel. The pilot
(N) on the backing flange will be against the wheel when the wheel is installed.
2 . Place the wheel on the backing flange, centering the wheel on the pilot.
3 . Install the threaded clamp nut with the pilot facing away from the wheel.
4 . Depress the spindle lock button and tighten clamp nut with a wrench.
5 . To remove the wheel, grasp the wheel and turn while depressing the spindle lock button.
WA R N I N G : When wheel is tightened, always make sure the clamp nut has rotated at least
1-1/2 turns to ensure proper thread engagement. Failure to do so could result in wheel dis -
mount and may result in injury.

SWITCH
C A U T I O N : Hold the side handle and body of the tool firmly to maintain control of the tool at
start up and during use and until the wheel stops rotating. Make sure the wheel has come to
a complete stop before laying the tool down.
PADDLE SWITCH (FIG. 6)
To turn the tool on, push the lock-off lever (B) toward the back of the tool, then depress the
paddle switch (A). The tool will run while the switch is depressed. Turn the tool off by releas-
ing the paddle switch.
WA R N I N G: Do not disable the lock-off lever. If the lock-off lever is disabled, the tool may
start unexpectedly when it is laid down.
C A U T I O N : Allow the tool to reach full speed before touching tool to the work surface. Lift
the tool from the work surface before turning the tool off.
SPINDLE LOCK
The spindle lock pin is provided to prevent the spindle from rotating when installing or remov-
ing wheels. Operate the spindle lock pin only when the tool is turned off, unplugged from the
power supply, and has come to a complete stop. Do not engage the spindle lock while the tool
is operating because damage to the tool will result. To engage the lock, depress the spindle
lock button and rotate the spindle until you are unable to rotate the spindle further.
USING CUTTING WHEELS (FIG. 7)
WA R N I N G : Do not use cutting wheels for surface grinding applications because these
wheels are not designed for side pressures encountered with surface grinding. Wheel break -
age and injury may result.
1 . Allow tool to reach full speed before touching tool to work surface.
2 . Apply minimum pressure to work surface, allowing tool to operate at high speed. Cutting
rate is greatest when the tool operates at high speed.
3. Once a cut is begun and a notch is established in the workpiece, do not change the
angle of the cut. Changing the angle will cause the wheel to bend and may cause wheel
breakage.
4 . Remove the tool from work surface before turning tool off. Allow the tool to stop rotating
before setting it down.
