IMPORTANT SAFETY RULES
W oodworking can be dangerous if safe and proper operating procedures are not followed. As with all machinery, there are cert ain
hazards involved with the operation of the product. Using the machine with respect and caution will considerably lessen the possi bility of personal injury . However, if normal safety precautions are overlooked or ignored, personal injury to the operator may result.
Safety equipment such as guards, push sticks, hold-downs, featherboards, goggles, dust masks and hearing protection can reduce
your potential for injury . But even the best guard won t make up for poor judgment, carelessness or inattention. Always use common
sense and exercise caution in the workshop. If a procedure feels dangerous, don t try it. Figure out an alternative procedure that feels
safer . REMEMBER: Your personal safety is your responsibility.
This machine was designed for cert ain applications only . Delt a Machinery strongly recommends that this machine not be modified
and/or used for any application other than that for which it was designed. If you have any questions relative to a p articular applica tion, DO N O T use the machine until you have first cont acted Delt a to determine if it can or should be performed on the product.

IMPORTANT SAFETY RULES FOR
DUST COLLECTOR S
INTRODUCTION
Dust Collectors work by moving large volumes of air at lower suction pressures than vacuum
cleaners. Delt a dust collectors are not designed to be used as high-suction cleaners; however ,
they are designed to help maint ain clean, safe conditions around dust-creating machines in work shops and factories. The flexible hose furnished with each unit can be connected directly into the
woodworking machine.
W ARNING: Basic precautions should
always be followed when using your dust collector.
To reduce the risk of injury, electrical shock or fire,
comply with the safety rules listed below:
1. READ and underst and the instruction manual before
operating the dust collector .
2. D O N O T leave the dust collector plugged into the
electrical outlet. Unplug dust collector from the outlet
when not in use and before servicing, changing bags,
unclogging and cleaning.
3. A L W A Y S turn the power switch OFF before unpluggi ng the dust collector .
4. W ARNING: TO REDUCE THE RISK O F ELECTRICALSHOCK, do not use on wet surfaces. Do not expose
to rain. S tore indoors.
5. FOLLOW all electrical and safety codes, including
the National Electric Code (NEC) and the Occup ational
Safety and Health Regulations (OSHA). All electrical
connections and wiring should be made by qualified
personnel only.
6. D O N O T use the dust collector to pick up flammable
or combustible liquids, such as gasoline. NEVER use the
dust collector near any flammable or combustible liquids.
7. U S E the dust collector to pick up wood materials
only . D O N O T use the dust collector to pick up met al
shavings, met al dust, or p arts.
8. NEVER use the dust collector to dissip ate fumes
or smoke. NEVER pick up anything that is burning or
smoking, such as cigarettes, matches or hot ashes.
9. U S E only as described in this manual. U S E only accessories recommended by Delt a.
10. D O N O T pull the dust collector by the power cord.
NEVER allow the power cord to come in cont act with
sharp edges, hot surfaces, oil or grease.
11. D O N O T unplug the dust collector by pulling on the
power cord. A LW A Y S grasp the plug, not the cord.
12. D O N O T handle the plug or dust collector with wet
hands.
13. REPLACE a damaged cord immediately. D O N O T
use a damaged cord or plug. If the dust collector is not
operating properly, or has been damaged, lef t out doors
or has been in cont act with water , return it to an
Authorized Service Center for service.
14. D O N O T use the dust collector as a toy. D O NOT
use near or around children.
15. D O N O T insert fingers or foreign object s into the
dust intake port. Keep hair , loose clothing, fingers, and all
body part s away from openings and moving p art s of the
dust collector .
16. D O N O T use the dust collector without the dust col lection bag in place and properly secured.
17. A L W A Y S use safety gates to cover dust port s when
the dust collector is not in use or mounted to a support ing surface for storage.
18. PERIODICALLY INSPECT dust bag for any cut s,
rip s or tears. NEVER operate the dust collector with a
damaged bag or vacuum hose.
19. The dust collector is designed for home use or light
commercial duty O N LY!
20. CONNECT dust collector to a properly grounded out let only . See grounding instructions.

ON/OFF SWITCH
The ON/OFF switch is conveniently located on the side
of the motor . To turn the dust collector ON push the
switch (A) Fig. 22, upward to the ON position. To turn
the dust collector OFF , push the switch down to the
OFF position.
CONNECTING DUST COLLECTOR TO
POWER SOURCE
Before connecting your dust collector to an electrical power system, be sure the motor rating
agrees with the electrical system it is to be connected to.
Fig. 20
Fig. 21
Fig. 22
SINGLE PHASE OPERATION
If the motor on your dust collector is wired for 1 1 5 V olt,
single phase, the power cord is equipped with a plug that
has two flat, p arallel current-carrying prongs, and one
longer round or U shaped ground prong which requires
a mating 3-conductor grounded type recept acle, as
shown in Fig. 20.
If the motor on your dust collector is wired for 230 V olt,
single phase, the power cord is equipped with a plug that
has two flat, current-carrying prongs in t andem, and one
round or U shaped longer ground prong. This is used
only with the proper mating 3-conductor grounding type
recept acle, as shown in Fig. 21.
When the three-prong plug on your dust collector is
plugged into a grounded 3-conductor recept acle, the
long ground prong on the plug cont act s first so the
machine is properly grounded before electricity reaches it.
CAUTION: IN ALL CASES, MAKE CERTAIN THE RECEPTACLE IN QUESTION IS PROPERLY GROUNDED.
IF YOU ARE NOT SURE,H AVE A CERTIFIED ELECTRICIAN CHECK T H E RECEPTACLE.

LOCKING SWITCH IN THE OFF POSITION
W e suggest when the dust collector is not in use that the ON/OFF switch be locked in the OFF position. This can be
done by grasping the switch toggle (B) Fig. 23, and pulling it out of the switch (A) as shown. W ith the switch toggle (B)
removed, the switch will not operate. However, should the switch toggle (B) Fig. 23, be removed while the machine is
running, it can be turned OFF, but cannot be rest arted without inserting the switch toggle (B) back into the switch.
MAINTENANCE
NOTE: MAKE CERTAIN THE MACHINE IS DISCONNECTED FROMTHEPOWER SOURCE.
The dust bag furnished with the dust collector features a zippered opening for fast and easy dust removal, as shown in
Fig. 24. IMPORTANT:The operator performing this cleaning function should always wear eye protective goggles. T h e
aluminum blower impeller and all sheet met al fittings are maintenance-free and should not require any maintenance
during the life of the unit.
Fig. 23
Fig. 24
M O TO R MAINTENANCE
Removing dust and dirt: Blow off the motor with low pres sure air to remove dust or dirt. Air pressure above 50 P.S.I.
should not be used as high pressure may damage insulation. IMPORTANT:The operator performing this cleaning function
should always wear eye protective goggles. Dust can cause excessive insulation temperatures.
