intended use only.
2) Do not use outdoors or on wet surfaces.
3) Do not operate this machine unless it is completely assembled.
4) Always use a three-wire electrical system connected to the electrical ground. For maximum
protection against electrical shock, use a circuit that is protected by a ground fault circuit
interrupter. Consult your electrical contractor.
5) To prevent electrical shock: Always remove the electrical plug from the electrical outlet
before performing any repairs, maintenance or cleanup and when leaving the machine
unattended.
6) To prevent electrical shock: Keep the machine surface dry; Do not subject to rain; Store the
machine in a dry building area; Clean the machine with a dry cloth only.
7) Machines can cause an explosion when near flammable materials and vapors. Do not use

GROUNDING INSTRUCTIONS:
This machine must be grounded. If it should malfunction or
break down, grounding provides a path of least resistance
for electric current to reduce the risk of electric shock. This
machine is equipped with a cord having an equipment-
grounding conductor and grounding plug. The plug must be
inserted into an appropriate outlet that is properly installed
and grounded in accordance with all local codes and
ordinances.
WARNING! - Improper connection of the
equipment-grounding conductor can result in a risk of
electric shock. Check with a qualified electrician or service
person if you are in doubt as to whether the outlet is properly
grounded. Do not modify the plug provided with the machine - if it will not fit the outlet; have a
proper outlet installed by a qualified electrician.
This machine is for use on a nominal 120-volt circuit, and has a grounded plug that looks like
the plug illustrated in figure A. A temporary adapter that looks like the adapter illustrated in
figures B and C may be used to connect this plug to a 2-pole receptacle as shown in figure B if a
properly grounded outlet is not available. The temporary adapter should be used only until a
properly grounded outlet (figure A) can be installed by a qualified electrician. The green colored
rigid ear, lug, or the like extending from the adapter must be connected to 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.
NOTE: In Canada, the use of a temporary adapter is not permitted by the Canadian Electrical
Code
EXTENSION CORDS:
Use only three-wire 16/3 or larger gauge approved extension cords that have three-prong
grounding type plugs and three-pole receptacles that accept the appliance’s plug. Replace or
repair any damaged cords or plugs.

THERMAL-PROTECTION INSTRUCTIONS:
This vacuum cleaner is equipped with a thermal-protection device, which will interrupt vacuum
motor circuit automatically to prevent the motor from overheating. Air restrictions for an
extended period will result in the vacuum motor shutting down. If this occurs, press the switch
to turn the vacuum to the OFF position and wait a minimum of 5 minutes for the motor to cool to
a safe temperature. Be sure to determine the cause of overheating and rectify the problem
before using the vacuum cleaner again or it will continue to overheat and shut down. In some
instances the vacuum motor circuit is interrupted because of high motor temperature caused by
a dirty dust bag or an airway blockage. Please unplug the vacuum and check the inner paper
dust bag and airway. If the dust bag is too dirty and clogged, replace it with a new one. If an
airway is blocked, please remove the blockage before reuse. The motor can be restarted when
it is cool.
REPAIR SERVICE:
When servicing, use an authorized person only. Use only identical replacement parts.
PREPARATION FOR OPERATION:
Please refer to drawing 1
1) Remove the cover (Item # 34) and cover seal ring (Item # 33), pull out the cloth filter bag
(Item # 31). Check to see that the filter guards (Item # 1, Item # 2 and Item # 3) have not
shifted during shipping.
2) Install an inner paper dust bag (Item # 32) inside of the outer cloth filter bag (Item # 31). At
the beginning of each shift, the bags should be checked. Empty or replace as necessary.
3) Note: never use a paper dust bag without the cloth dust bag.
4) Place the cover seal ring (Item # 33) on the dust bag’s opening (Item # 32).
5) Replace the cover (Item # 34) and clip the sunken edge of the cover tight by pushing
downward the cover clip (Item # 7).
6) Push the connector tube (Item # 35) into the cover (Item # 34).
7) Check the wear on the cord by the vacuum body and at the plug. Pass the power supply

MAINTENANCE
Good maintenance procedures assure better operation, fewer repairs and longer life for
your machine.
WARNING! - DISCONNECT THE ELECTRICAL PLUG OF THE
MACHINE FROM THE ELECTRICAL OUTLET BEFORE DOING ANY
CLEANUP, REPAIRS OR MAINTENANCE OF THE MACHINE AND WHEN

CLEAN THE MACHINE AFTER EACH USE:
1) Each week, rinse, dry and return the foam (Item # 22) at the bottom of the vacuum tank
below the vacuum motor.
2) Clean the vacuum tank: Release the clamps on each side of the top of the vacuum tank.
Lift the filter assembly out of the vacuum tank and set aside. Wipe the inside and outside of
the vacuum tank with a clean dry cloth.
3) Empty and check the filter assembly: Empty the recovered soilage into a suitable container
and remove and shake the cloth filter bag to remove clinging dirt. Lightly brush the inside of
the cloth filter bag to remove embedded dirt. Check the cloth filter bag for tears or holes;
repair or replace if necessary. Install a clean paper dust bag into assembly into the cloth
filter bag and place them back into the vacuum tank.
ELECTRICAL CABLE:
Check the cord for any nicks, cuts or damage. Report these to your supervisor for correction.
VACUUM TANK ASSEMBLY:
1) Gaskets: Clean the Cover Seal Ring gasket.
2) Vacuum Motor Guards: Inspect for dirt or damage and replace if damaged or filled with dirt.

FILTER MAINTENANCE:
1) Check the paper dust bag (Item # 32) each time you start and finish vacuuming. A clogged
and dirty dust bag restricts airflow and results in reduced suction and overheating.
2) While vacuuming, stop every two hours or as needed to shake out the paper dust bag (Item
# 32). Replace the paper dust bag when necessary. Note: Lift both paper dust bag and
cloth filter bag out at the same time to avoid ripping the paper dust bag, especially when it is
full.
3) Once a month (or more often if necessary) hand or machine wash the cloth dust bag (Item #
31) and let it AIR DRY. DO NOT PUT IT IN A DRYER.
4) Once a month, or more often if necessary, clean the foam filter (Item # 2) between the motor
guards, located inside the vacuum tank under the paper and cloth dust bag. To do this
remove the top piece of the motor guard (Item # 1) and remove the foam filter (Item # 2).
Shake it out, rinse it and let it air dry thoroughly. Before the next use, re-install a DRY foam
filter (Item # 2). Replace with new foam filter if it becomes worn or damaged. Re-install
motor guard (Item # 1) by firmly snapping the guard in place.
5) Each week rinse and air dry the foam filter (Item # 22) at the bottom of the vacuum tank
below the vacuum motor. To do this pull out the round rubber support (Item # 21) and
remove foam filter (Item # 22). Rinse the foam filter and let it air dry thoroughly. Before the
next use, re-install foam filter (Item # 22) then reinstall round rubber support (Item # 22) into
the canister to support the foam filter.
