Warnings
1. Read and understand the entire owners manual before attempting assembly or operation.
2. Read and understand the warnings posted on the machine and in this manual. Failure to comply with all of
these warnings may cause serious injury.
3. Replace the warning labels if they become obscured or removed.
4. This dust collector is designed and intended for use by properly trained and experienced personnel only. If
you are not familiar with the proper and safe operation of a dust collector, do not use until proper training
and knowledge have been obtained.
5. Do not use this dust collector for other than its intended use. If used for other purposes, WMH Tool Group
disclaims any real or implied warranty and holds itself harmless from any injury that may result from that
use.
6. Always wear approved safety glasses/face shields while using this dust collector. Everyday eyeglasses
only have impact resistant lenses; they are not safety glasses.
7. Before operating this dust collector, remove tie, rings, watches and other jewelry, and roll sleeves up past
the elbows. Remove all loose clothing and confine long hair. Non-slip footwear or anti-skid floor strips are
recommended. Do not wear gloves.
8. Wear ear protectors (plugs or muffs) during extended periods of operation.
9. Some dust created by power sanding, sawing, grinding, drilling and other construction activities contain
chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these
chemicals are:
• Lead from lead based paint.
• Crystalline silica from bricks, cement and other masonry products.
• Arsenic and chromium from chemically treated lumber.
Your risk of exposure varies, depending on how often you do this type of work. To reduce your exposure
to these chemicals, work in a well-ventilated area and work with approved safety equipment, such as face
or dust masks that are specifically designed to filter out microscopic particles.
10. Do not operate this machine while tired or under the influence of drugs, alcohol or any medication.
11. Make certain the switch is in the OFF position before connecting the machine to the power supply.
12. Make certain the machine is properly grounded.
13. Make all machine adjustments or maintenance with the machine unplugged from the power source.
14. Remove adjusting keys and wrenches. Form a habit of checking to see that keys and adjusting wrenches
are removed from the machine before turning it on.
15. Keep safety guards in place at all times when the machine is in use. If removed for maintenance purposes,
use extreme caution and replace the guards immediately.
16. Check damaged parts. Before further use of the machine, a guard or other part that is damaged should be
carefully checked to determine that it will operate properly and perform its intended function. Check for
alignment of moving parts, binding of moving parts, breakage of parts, mounting and any other conditions
that may affect its operation. A guard or other part that is damaged should be properly repaired or
replaced.
17. Provide for adequate space surrounding work area and non-glare, overhead lighting.
18. Keep the floor around the machine clean and free of scrap material, oil and grease.
19. Keep visitors a safe distance from the work area. Keep children away.

20. Make your workshop child proof with padlocks, master switches or by removing starter keys.
21. Give your work undivided attention. Looking around, carrying on a conversation and “horse-play” are
careless acts that can result in serious injury.
22. Do not use the dust collector for anything except wood dust. Materials such as liquids, metal shavings,
metal dust, screws, glass, plastic or rock can cause sparks and/or damage when coming into contact with
any part of the dust collector.
23. Use recommended accessories; improper accessories may be hazardous.
24. Maintain tools with care. Follow instructions for lubricating and changing accessories.
25. Turn off the machine before cleaning. Use a brush or compressed air to remove chips or debris — do not
use your hands.
26. Do not stand on the machine. Serious injury could occur if the machine tips over.
27. Never leave the machine running unattended. Turn the power off and do not leave the machine until it
comes to a complete stop.
28. Remove loose items and unnecessary work pieces from the area before starting the machine.

Assembly
Base
1. Install four casters to the under side of the base as
pictured in Fig. 2.
2. Thread the hex nut (B, Fig. 1) onto the caster
shaft. Then slide the lock washer (A, Fig. 1) over
the caster shaft. Thread the caster shaft into the
threaded hole on the underside of the base, turn
until snug. Tighten the nut (B, Fig. 1) against the
base with a 14mm wrench. This will give the
caster proper clearance.
Motor and Fan Assembly
3. Place the base with casters on the ground. Attach
the motor and fan assembly (A, Fig. 2) to the base
using four M8 x 16 hex cap screws, four M8 flat
washers (B, Fig. 2), and a 13mm wrench.
The dust collector must not be
connected to the power source during assembly.
Failure to comply may result in serious injury!
4. Attach inlet guard (A, Fig. 3) to fan housing using
eight M6x 12 pan head screws (B, Fig.3). Press
the inlet ports (C, Fig. 3) onto the inlet guard until it
snaps into place.
To reduce the risk of injury from
moving parts, always keep inlet port covered with
the caps provided, if they are not connected to a
hose. Failure to comply may result in serious
injury!

Connector Housing
5. Attach three support brackets (A, Fig. 4) to the
base using six M8 x 16 hex cap bolts and six M8
flat washers (B, Fig. 4). Hand-tighten only at this
time.
6. Install the housing (A, Fig. 5) to two support
brackets using four M8 x 16 hex cap bolts, eight
M8 flat washers, and four M8 hex nuts (B, Fig.5).
Be sure hose opening faces fan housing. Be sure
hose opening faces fan housing.
7. Before attaching third support bracket place the
hanger bracket (D, Fig.5) between the support
bracket and the housing.
Note: The hanger bracket is used in models
DC-1200A/RC only.
Tighten all nuts and bolts at this time with a 13mm
wrench.
Hose
8. Attach the hose (A, Fig. 6) between the fan
housing and the collector housing with two clamps
(B, Fig. 6). Tighten the clamps to secure the hose.
If you are assembling the DC-1200A/RC Dust
Collector, proceed to the next section. If you are
