English FIG. 15 F R Q NOTICE: Failure to properly seat the wheel against backing flange before turning the tool on may result in damage to the tool or the wheel. NOTE: Adjust the guard skirt so that only 1/8" (3.17 mm) of the wheel is exposed by loosening the bolts, allowing the guard to lengthen. Tighten the guard skirt bolts securely before using the grinder. USING A FLARING CUP WHEEL (FIG. 16) Flaring cup wheels are designed for heavy material removal. 1. Allow the tool to reach full speed before touching tool to work surface. FIG. 16 2. Apply minimum pressure to work surface, allowing the tool to operate at high speed. 3. Maintain a 5˚ to 10˚ angle between the tool and the work surface. 5˚-10˚ 4. Continuously move the tool in a forward and back motion to avoid creating gouges in the work surface. 5. Remove the tool from work surface before turning tool off. Allow the tool to stop rotating before setting it down. Mounting and Using Cutting FIG. 17 (Type 1) Wheels I Cutting wheels include diamond wheels and abrasive discs. Abrasive cutting wheels for metal and concrete use are available. Diamond blades for concrete cutting can also be used. WARNING: A closed, cutting wheel guard is not included with this tool. Cutting wheels require proper flanges and guards. A 7" cutting guard, D284931, is available as an accessory and includes proper, matching flanges. Failure to use proper flange and guard can result in injury resulting from wheel breakage and wheel G contact. MOUNTING CLOSED (TYPE 1) GUARD (FIG. 17, 18) 1. Open the guard latch (I), and align the lugs with slots on the gear case cover. Position the guard facing backward, as shown. 2. Push the guard down until the guard lug engages and rotates freely in the groove on the gear case hub. 3. Rotate guard (G) 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 guard latch in open position. FIG. 18 NOTE: 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 (J) with the guard latch in the closed position. J 17

NOTICE:
Failure to properly seat the wheel against backing flange
before turning the tool on may result in damage to the tool or the
wheel.
NOTE:
Adjust the guard skirt so that only 1/8" (3.17 mm) of the wheel
is exposed by loosening the bolts, allowing the guard to lengthen.
Tighten the guard skirt bolts securely before using the grinder.
USING A FLARING CUP WHEEL (FIG. 16)
Flaring cup wheels are designed for heavy material removal.
1. Allow the tool to reach full speed before touching tool to work
surface.
2. Apply minimum pressure to work surface,
FIG. 16

–
10˚
allowing the tool to operate at high speed.
3. Maintain a 5˚ to 10˚ angle between the tool
and the work surface.
4. Continuously move the tool in a forward and back motion to avoid
creating gouges in the work surface.
5. Remove the tool from work surface before turning tool off. Allow
the tool to stop rotating before setting it down.
Mounting and Using Cutting
(Type 1) Wheels
Cutting wheels include diamond wheels and
FIG. 17
I
G
abrasive discs. Abrasive cutting wheels for
metal and concrete use are available. Diamond
blades for concrete cutting can also be used.
WARNING:
A closed, cutting wheel guard
is not included with this tool. Cutting wheels
require proper flanges and guards. A 7" cutting
guard, D284931, is available as an accessory
and includes proper, matching flanges. Failure
to use proper flange and guard can result in
injury resulting from wheel breakage and wheel
contact.
MOUNTING CLOSED (TYPE 1) GUARD (FIG. 17, 18)
1. Open the guard latch (I), and align the lugs with slots on the gear
case cover. Position the guard facing backward, as shown.
2. Push the guard down until the guard lug engages and rotates
freely in the groove on the gear case hub.
3. Rotate guard (G) 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
guard latch in open position.
NOTE:
The guard is pre-adjusted to the
FIG. 18
J
diameter of the gear case hub at the factory. If,
after a period of time, the guard becomes
loose, tighten the adjusting screw (J) with the
guard latch in the closed position.
