Maintenance - DeWalt DWE4012 Instruction Manual

English
nOTE: Only those dust masks suitable for working with
lead paint dust and fumes should be used. Ordinary
painting masks do not offer this protection. See your local
hardware dealer for the proper NIOSH-approved mask.
3. NO EATING, DRINKING or SMOKING should be done in
the work area to prevent ingesting contaminated paint
particles. Workers should wash and clean up BEFORE
eating, drinking or smoking. Articles of food, drink, or
smoking should not be left in the work area where dust
would settle on them.
Environmental safety
1. Paint should be removed in such a manner as to
minimize the amount of dust generated.
2. Areas where paint removal is occurring should be sealed
with plastic sheeting of 4 mm thickness.
3. Sanding should be done in a manner to reduce tracking
of paint dust outside the work area.
Cleaning and Disposal
1. All surfaces in the work area should be vacuumed
and thoroughly cleaned daily for the duration of
the sanding project. Vacuum filter bags should be
changed frequently.
2. Plastic drop cloths should be gathered up and disposed
of along with any dust chips or other removal debris.
They should be placed in sealed refuse receptacles and
disposed of through regular trash pick-up procedures.
During clean-up, children and pregnant women should
be kept away from the immediate work area.
3. All toys, washable furniture and utensils used by children
should be washed thoroughly before being used again.
Edge Grinding and Cutting

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.

CAUTION: Wheels used for edge grinding and
cutting may break or kick back if they bend or twist
while the tool is being used. In all edge grinding/
cutting operations, the open side of the guard must be
positioned away from the operator.
NOTICE: Edge grinding/cutting with a Type 27 wheel
must be limited to shallow cutting and notching—less
than 1/2" (13 mm) in depth when the wheel is new.
Reduce the depth of cutting/notching equal to the
reduction of the wheel radius as it wears down. Refer
to the Accessories Chart for more information. Edge
grinding/cutting with a Type 1/41 wheel requires usage
of a Type 1/41 guard.
1. Allow the tool to reach full speed before touching the
tool to the work surface.
2. Apply minimum pressure to the work surface, allowing
the tool to operate at high speed. Grinding/cutting rate is
greatest when the tool operates at high speed.
3. Position yourself so that the open-underside of the wheel
is facing away from you.
12
4. 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. Edge grinding wheels are not designed
to withstand side pressures caused by bending.
5. Remove the tool from the work surface before turning
the tool off. Allow the tool to stop rotating before laying
it down.

MAINTENANCE


WARNING: To reduce the risk of serious personal
injury, turn unit off and disconnect it from
power source before making any adjustments or
removing/installing attachments or accessories.
An accidental start‑up can cause injury.
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.
Cleaning

WARNING: Blow dirt and dust out of all air vents with
clean, dry air at least once a week. To minimize the risk
of eye injury, always wear ANSI Z87.1 approved eye
protection when performing this procedure.

WARNING: Never use solvents or other harsh
chemicals for cleaning the non‑metallic parts of the
tool. These chemicals may weaken the plastic materials
used in these parts. Use a cloth dampened only with
water and mild soap. Never let any liquid get inside the
tool; never immerse any part of the tool into a liquid.
Accessories

WARNING: Since accessories, other than those offered
by D WALT, have not been tested with this product,
e
use of such accessories with this product could be
hazardous. To reduce the risk of injury, only D
recommended accessories should be used with
this product.

WARNING: Accessories must be rated for at least
the speed recom mended on the tool warning label.
Wheels and other accessories running over their
rated accessory speed may fly apart and cause injury.
Threaded accessories must have a 5/8"‑11 hub. Every
unthreaded accessory must have a 7/8" (22 mm) arbor
hole. If it does not, it may have been designed for a
circular saw and should not be used. Use only the
accessories shown in the Accessories Chart of this
manual. Accessory ratings must always be above tool
speed as shown on tool nameplate.

WARNING: Do not use a bonded abrasive wheel that
is past its expiration (EXP) date as marked near center
of wheel (if provided). Expired wheels are more likely to
