DeWalt DWE4884 Instructions Manual page 25


WARNING:
• Ensure all materials to be ground or cut are secured
in place.
• Use clamps or a vice to hold and support the
workpiece to a stable platform. It is important to
clamp and support the workpiece securely to prevent
the movement of the workpiece and loss of control.
Movement of the workpiece or loss of control may
create a hazard and cause personal injury.
• Secure the workpiece. A workpiece clamped with
clamping devices or in a vice is held more secure than
by hand.
• Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kickback.
Large workpieces tend to sag under their own weight.
Supports must be placed under the workpiece near the
line of cut and near the edge of the workpiece on both
sides of the wheel.
• Always wear regular working gloves while operating
this tool.
• The gear case becomes very hot during use.
• Apply only a gentle pressure to the tool. Do not exert
side pressure on the disc.
• Avoid overloading. Should the tool become hot, let it
run a few minutes under no load condition.
• The best grinding results are achieved when setting
the machine at an angle of 90°. Move the machine
back and forth with moderate pressure. In this
manner, the workpiece will not become too hot, does
not discolour and no grooves are formed.

WARNING: Grasp tool firmly with both hands to maintain
control of the tool at start up and during use and until the
wheel or accessory stops rotating. Make sure the wheel
has come to a complete stop be fore laying the tool down.
Put the work in a vise or clamp it securely. Use a face mask
over the nose and mouth if the operation raises dust. Treat
the wheel with respect. Do not jam the wheel into the work or
use unnecessary pressure. Grind only on the face of the wheel
unless you have a special wheel specifically make to permit
grinding on the side of the wheel.
Proper Hand Position (Fig. C)

WARNING: To reduce the risk of serious personal injury,
ALWAYS use proper hand position as shown.

WARNING: To reduce the risk of serious personal
injury, ALWAYS hold securely in anticipation of a
sudden reaction.
Proper hand position requires one hand on the body, with the
other hand on the neck of the die grinder, as shown in Figure C.
Install Grinding Wheels (Fig. A, B, D)

WARNING: Accessories must be rated at least equal to the
maximum speed marked on the tool. Accessories running
faster than their rated speed can break and fly apart.

WARNING: Accessories must be within the capacity rating
marked on the tool. Incorrectly sized accessories cannot be
adequately controlled.

WARNING: Do not use accessories with a mandrel length
exceeding 40 mm. Ensure that the exposed mandrel
length is no more than 10 mm after inserting accessory
into collet.

WARNING: Never tighten the collet nut without an
accessory in the collet.
1. Hold the spindle 2 using the 13 mm wrench
2. Loosen the collet nut 3 with the 17 mm wrench
turning it counterclockwise.
3. Insert the shank of the accessory (minimum 20 mm) into
the collet.
4. Securely tighten the collet nut
provided.
nOtE: The shank overhang, amount that sticks out past the
collet nut 3 , should not exceed 10 mm. Refer to Figure D.
To remove the accessory, proceed in reverse order.
Metal Applications
When using the tool in metal applications, make sure that a
residual current device (RCD) has been inserted to avoid residual
risks caused by metal swarf.
If the power supply is shut off by the RCD, take the tool to
authorised D WALT repair agent.
e

WARNING: In extreme working conditions, conductive
dust can accumulate inside the machine housing when
working with metal. This can result in the protective
insulation in the machine becoming degraded with a
potential risk of an electrical shock.
To avoid build-up of metal swarf inside the machine, we
recommend to clear the ventilation slots on a daily basis.
See Maintenance.
MAINTENANCE
Your D WALT power tool has been designed to operate
e
over a long period of time with a minimum of maintenance.
Continuous satisfactory operation depends upon proper tool
care and regular cleaning.

WARNING: To reduce the risk of serious personal
injury, turn tool off and disconnect tool from power
source before making any adjustments or removing/
installing attachments or accessories. An accidental
start-up can cause injury.
Motor Brushes
Keep brushes clean and sliding freely in their guides. Carbon
brushes have varying symbols stamped into them, and if the
brush is worn down to the line closest to the spring, they must
be replaced. New brush assemblies are available at your local
service center.
