IMPORTANT SAFETY INSTRUCTIONS
WARNING
Read all safety warnings and all
instructions. Failure to follow the
warnings and instructions may result in serious injury. Save all warnings and instructions for future
reference.
•Use the station and accessories in accordance
with these instructions and in the manner intended, taking into account the working conditions.
Use of the station for operations different from those
intended could result in a hazardous situation.
•Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
•Fully assemble the station according to the as-
sembly instructions. Do not leave off any pieces.
•Do not modify the station in any way. Use only
specifically recommended accessories. Drilling
holes or modifying the station will lower the load
capacity, which can cause the station to collapse,
resulting in injury.
•Lock wheels when station is not being moved.
Unlocked wheels can allow the station to move
unexpectedly.
•Keep the station on a level surface. Do not load,
unload, or park station on an incline. The station
may become unbalanced and tip, resulting in injury.
•Always balance the station load to avoid tipping.
Unbalanced stations are more likely to tip when being moved or when using the station work surfaces.
Evenly distribute the weight front to back and side
to side. To help prevent the station from tipping,
load the product starting with the bottom drawers.
• Do not exceed the maximum product weight,
including contents. Do not exceed the maximum
weight for each drawer. Overloaded stations can
tip, collapse, or damage drawer slides.
• Do not open more than one drawer at a time.
Station may tip, causing injury.
•Keep children and bystanders away while load-
ing, unloading, and moving the station. Distrac-
tions can cause you to lose control.
•Only lift the station according to the instructions
in this manual. Other methods may be dangerous,
resulting in injury.
• Only transport the station when empty. Properly
secure when transporting.
• Do not mount the station on a truck bed or any
other moving object.
• Lock all drawers before rolling the station. The
drawers could come open and make the station
unstable and tip.
• Only roll the station short distances by using
the handle provided.
• Secure all items before rolling the station. Loose
items could shift, causing the station to become
unstable.
• Do not use drawers as steps. Do not stand
on the station. Station may tip, causing injury.
• Do not step on side shelf. Shelf may collapse or
break. Station may tip, causing injury.
•Do not use station in explosive atmospheres,
such as in the presence of ammable liquids, gases
or dust. This equipment has internal arcing or spark-
ing parts. Station should not be located in a recessed
area or below oor level.
•Station plugs must match the outlet. Never modify the plug in any way. Do not use any adapter
plugs with earth (grounded) chest/cabinet power
strips. Unmodied plugs and matching outlets will
reduce risk of electric shock.
•Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
•Maintain station. Check for misalignment or binding wheels, breakage or bending of drawer slides or
other parts and any other condition that may affect
the station's operation. Do not use damaged station.
•Maintain labels and nameplates. These carry
important information. If unreadable or missing,
contact a MILWAUKEE service facility for a free
replacement.
•Have your station serviced by a qualied repair
person using only identical replacement parts.
This will ensure that the safety of the station is
maintained.

GROUNDING
WARNING
Improperly connecting the grounding wire can result in the risk of
electric shock. Check with a qualied electrician
if you are in doubt as to whether the outlet is
properly grounded. Do not modify the plug provided with the station. Never remove the grounding prong from the plug. Do not use the station
if the cord or plug is damaged. If damaged, have
it repaired before use. If the plug will not t the
outlet, have a proper outlet installed by a qualied
electrician.
Stations with Three Prong Plugs
Stations marked “Grounding Required” have a
power strip with a three wire cord and three prong
grounding plug. The plug must be connected to a
properly grounded outlet (See Figure A). If the
power strip should electrically malfunction or break
down, grounding provides a low resistance path to
carry electricity away from the user,
Fig. A
reducing the risk of electric shock.
The grounding prong in the plug is
connected through the green wire
inside the cord to the grounding system in the power strip. The green wire in the cord
must be the only wire connected to the power strip's
grounding system and must never be attached to an
electrically “live” terminal.
Your power strip must be plugged into an appropriate
outlet, properly installed and grounded in accordance
with all codes and ordinances. The plug and outlet
should look like those in Figure A.

OPERATION
WARNING
To avoid injury or property damage,

you need to lift, empty the station and then place
straps or forks inside and next to casters. Do not lift
loaded stations. Be sure all bystanders are moved
away before lifting station.
Mounting Chargers

charger mounting bosses, located below the power
strip. The charger mounts are suitable for holding
MILWAUKEE M18™ & M12™ Multi Voltage chargers
as well as M18™ chargers. To mount a charger,
install a screw (AA) into each boss, then slide the
charger's key-hole slots over the screws. Slide the
charger toward the oor to lock it onto the screws.

Points
Maintaining the Drawers
1. Periodically clean the drawer with a mild detergent
and water.
2. Remove grease and oil in drawer with a standard,
nonammable cleaning uid.
3. The use of drawer liners is recommended to
protect the nish inside the drawers and make
the drawers easier to clean. Drawer liners can be
cleaned with soap and water.
4. Lubricate the slides semi-annually with general
purpose grease or equivalent.

Cleaning
This steel product has been coated with industrial
powder coating for a durable nish. To help protect
the powder coated nish, do not allow harsh chemi-
cals (oil, grease or other chemical) to remain on the
powder coating surface. Use a glass cleaner to clean
and maintain all surfaces of powder coating.
Keep the station handles and wheels clean, dry and
free of oil or grease. Use only mild soap and a damp
cloth to clean your station since certain cleaning
agents and solvents are harmful to plastics. Some of
these include: gasoline, turpentine, lacquer thinner,
chlorinated cleaning solvents, ammonia and household detergents containing ammonia. Never use
ammable or combustible solvents around station.
