DeWalt DWE4559CN instruction manual Mounting Cutting Wheels FIG, Using Cutting Wheels

MOUNTINGCLOSED(TYPE1)GUARD			FIG,20	_N
1.	Open the guard latch (M), and align the		M
	lugs (N) on the guard with the slots on
	the hub (O). This will align the lugs with
	slots on the gear case cover. Position
	the guard facing backward.
2.	Push the guard down until the	guard
	lug engages and rotates freely	in the		O
	groove on the gear case hub.
3.	Rotate guard (F) into desired working			F

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 with the guard latch in open position.

5.To remove the guard, follow the procedure above in reverse order.

MOUNTING CUTTING WHEELS (FIG. 22)

CAUTION: Matching diameter threaded backing flange and clamp nut (included with tool) must be used for cutting wheels.

1.Remove soft mount (G).

2.Install wheel backing flange, aligning flats on spindle (X)with flats on backing flange (Q).

3.Place the wheel on the backing flange, centering the wheel on the backing flange pilot.

4.Install the clamp nut, ensuring that the wheel remains centered on the backing flange.

5.Depress the spindle lock button and tighten clamp nut with wrench.

6.Reverse the above procedure to remove the wheel.

FIG.22

NOTE" The guard is pre-adjusted to the FIG.21
diameter of the gear case hub at the factory.	P
If, after a period of time, the guard becomes
loose, tighten the adjusting screw (P) with
the guard latch in the closed position with
guard installed on the tool.

NOTICE: To reduce the risk of damage

to the tool, do not tighten adjusting screw with guard latch in open position. Undetectable damage to guard or mounting hub may result.

USING CUTTING WHEELS

i_,WARNING: Do not use edge grinding/cutting wheels for surface grinding applications because these wheels are not designed for side pressures encountered with surface grinding. Wheel breakage 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.
