SAFETY INSTRUCTIONS
WARNING:
When using dust collector, safety precautions
should always be followed to reduce the risk of fire, electric
shock, and personal injury, including the followings:
READ ALL INSTRUCTIONS BEFORE USING THIS DUST COLLECTOR.
1. PROPER GROUNDING. This tool should be grounded while in use t o protect
the operator from electric shock. Connect t o a properly grounded outlet only.
See “Grounding Instructions”.
2. GUARD AGAINST ELECTRIC SHOCK. Prevent body contact with grounded
surfaces. For example; pipes, radiators, ranges, ref rigerator enclosures.
3. This dust collector is intended for commercial use.
4. Do not use the dust collector without the filter. Replace a damaged filter
immediately.
5. EXTENSION CORDS: Use only three-wire extension cords which have threeprong grounding-type plugs and three-pole receptacles which accept the
tool’s plug. For outdoor applications require an extension cord suitable for
outdoor use. Replace or repair damaged or worn cord immediately.
6. VOLTAGE WARNING: Before connecting the dust collector t o a power source
(receptacle, outlet, etc.) be sure the voltage supplied is the same as that
specified on the nameplate of the dust collector. A power source with voltage
greater than that specified for the dust collector can result in SERIOUS
INJURY t o the user - as well as damage t o the dust collector. If in doubt,
DO NOT PLUG IN THE DUST COLLECTOR. Using a power source with voltage
less than the nameplate rating is harmful t o the motor.
7 . Do not handle plug or dust collector with wet hands.
8 . Always switch off and unplug the dust collector after each use and when
power fails.
9. Wear a dust mask during dusty operations and a special respirator when
vacuuming anything which may possibly endanger your breathing.
IO. This
is a dry pick-up backpack type dust collector for collecting dust exhausted from various types of electric power tools such as rotary hammers
and sanders. Do n o t attempt t o pick up liquids, wet dirt, flammable materials, sparks, fire works, lighted cigarettes, hot ashes, sharp materials such
as razors, needles, broken glass or the like.
11. Do not vacuum toxic, carcinogenic, combustible or other hazardous materials such as asbestos, arsenic, barium, beryllium, lead, pesticides or other
health endangering materials.
12. NEVER USE THE DUST COLLECTOR IN THE VICINITY OF GASOLINE, GAS,
PAINT, ADHESIVES OR OTHER HIGHLY EXPLOSIVE SUBSTANCES. The
2
switch emits sparks when turned ON and OFF, and so does the motor
commutator during operation. A dangerous explosion may result.
13. Do not allow t o be used as a toy. Close attention is neccessary when used
by or near children.
14. Use only as described in this manual. Use only MAKITA's recommended
attachments.
15. Never use the dust collector in the rain. When not in use, store the dust
collector indoors.
16. Do not use close t o heat source (stoves, etc.). This can cause discoloration
and/or damage t o the dust collector enclosures.
17. Do not block cooling vents or intake hole during operation. Do not attempt
t o pick up large items which may clog the dust collector.
18. Keep proper footing and balance at all times.
19. Use extra care when cleaning on stairs.
20. DON'T ABUSE CORD. Never carry the dust collector by cord or yank it t o
disconnect from receptacle. Keep cord away from heat, oil, and sharp edges.
Inspect cords periodically and if damaged, have repaired by authorized service
facility.
21. Do not fold, tug nor step on the hose.
22. Stop the dust collector immediately if you notice poor performance, unusual
vibrations or anything abnormal during operation.
23. DISCONNECT THE DUST COLLECTOR. When not in use, before servicing,
and when changing accessories.
24. Use the cleaning lever frequently t o clear the dust from the filter. Empty the
contents of the dust compartment before full.
25. Clean and service the dust collector immediately after each use t o keep it
in tiptop operating condition.
26. Wear hearing protection during extended periods of operations.
27. Never place the hose over or near your mouth or nostrils.
28. REPLACEMENT PARTS. When servicing, use only identical replacement parts.
29. Be kind t o your dust collector. Rough handling can cause breakage of even
the most sturdily built dust collector.
30. Wipe the dust collector off with a soft cloth dampened in detergent solution. Never use thinner or benzine. This can cause discoloration and cracks
in the dust collector enclosures.
SAVE THESE INSTRUCTIONS.

GROUNDING INSTRUCTIONS
This appliance must be grounded. If it should malfunction or breakdown, grounding provides a path of least resistance for electric current t o reduce the risk of
electric shock. This appliance is equipped with a cord having an equipmentgrounding conductor and grounding plug. The plug must be plugged into an
appropriate outlet that is properly installed and grounded in accordance w i t h all
local codes and ordinances.
WARNING

conductor can result in a risk of electric shock. Check w i t h a qualified electrician or service person i f you are in doubt as t o whether the outlet is properly
grounded. Do not modify the plug provided with the appliance - i f it will not
fit the outlet, have a proper outlet installed by a qualified electrician.
This appliance is for use on a nominal 120-volt circuit, and has a grounded plug
that looks like the plug illustrated in Fig. A. A temporary adapter that looks like
the adapter illustrated in Fig. B and C may be used t o connect this plug t o a 2-pole
receptacle as shown in Fig. B if a properly grounded outlet is not available. The
temporary adapter should be used only until a properly grounded outlet (Fig. A)
can be installed by a qualified electrician. The green colored rigid ear, lug, or the
like extending from the adapter must be connected t o a permanent ground such
as a properly grounded outlet box cover. Whenever the adapter is used, it must
be held in place by a metal screw.
