long-term respiratory damage. Be aware of dust
hazards associated with each workpiece material,
and always wear a NIOSH-approved respirator to
reduce your risk.
HEARING PROTECTION. Always wear hearing protection when operating or observing loud
machinery. Extended exposure to this noise
without hearing protection can cause permanent
hearing loss.
REMOVE ADJUSTING TOOLS. Tools left on
machinery can become dangerous projectiles
upon startup. Never leave chuck keys, wrenches,
or any other tools on machine. Always verify
removal before starting!
USE CORRECT TOOL FOR THE JOB. Only use
this tool for its intended purpose—do not force
it or an attachment to do a job for which it was
not designed. Never make unapproved modifications—modifying tool or using it differently than
intended may result in malfunction or mechanical
failure that can lead to personal injury or death!
AWKWARD POSITIONS. Keep proper footing
and balance at all times when operating machine.
Do not overreach! Avoid awkward hand positions
that make workpiece control difficult or increase
the risk of accidental injury.
CHILDREN & BYSTANDERS. Keep children and
bystanders at a safe distance from the work area.
Stop using machine if they become a distraction.
FORCING MACHINERY. Do not force machine.
It will do the job safer and better at the rate for
which it was designed.
NEVER STAND ON MACHINE. Serious injury
may occur if machine is tipped or if the cutting
tool is unintentionally contacted.
STABLE MACHINE. Unexpected movement during operation greatly increases risk of injury or
loss of control. Before starting, verify machine is
stable and mobile base (if used) is locked.
USE RECOMMENDED ACCESSORIES. Consult
this owner’s manual or the manufacturer for recommended accessories. Using improper accessories will increase the risk of serious injury.
UNATTENDED OPERATION. To reduce the
risk of accidental injury, turn machine OFF and
ensure all moving parts completely stop before
walking away. Never leave machine running
while unattended.
MAINTAIN WITH CARE. Follow all maintenance
instructions and lubrication schedules to keep
machine in good working condition. A machine
that is improperly maintained could malfunction,
leading to serious personal injury or death.
CHECK DAMAGED PARTS. Regularly inspect
machine for any condition that may affect safe
operation. Immediately repair or replace damaged
or mis-adjusted parts before operating machine.
MAINTAIN POWER CORDS. When disconnecting cord-connected machines from power, grab
and pull the plug—NOT the cord. Pulling the cord
may damage the wires inside. Do not handle
cord/plug with wet hands. Avoid cord damage by
keeping it away from heated surfaces, high traffic
areas, harsh chemicals, and wet/damp locations.
GUARDS & COVERS. Guards and covers reduce

SECTION 3: OPERATIONS
Sandblasting presents a real hazard of silicosis and other lung contamination injuries! These
Injuries are permanent and can get worse over time. If you use sandblasting equipment without
the proper headgear, eye protection, and respirator, your lungs and eyes may become irreversibly
contaminated. DO NOT use this sandblaster unless you know how to use it, protect yourself
correctly, and keep all unprotected bystanders away. For latest types of protective equipment and
acceptable respirator types, contact your local OSHA or NIOSH office.
Operation Safety
NEVER sand blast with the doors open,
point the gun at yourself or anyone else, or
attempt to service any part of this machine
while it is plugged in or connected to air
pressure. ALWAYS disconnect the blast
cabinet from power and air pressure when
not in use, or during maintenance or adjustments. Ignoring this warning may lead to
severe injur y.
NOTICE
If you have never used this type of equipment before, WE STRONGLY RECOMMEND
that you read books, trade magazines, or
get formal training before beginning any
projects. Regardless of the content in this
section, Grizzly Industrial will not be held
liable for accidents caused by lack of training.
Basic Operation
The Model T27158 Sandblaster is equipped with
an industrial-duty blast nozzle, tank, ball valves,
hoses, pressure gauge, and water separator.
To use the sandblaster:
1. PUT ON safety glasses, gloves, and
respirator. Always wear these protective
items when operating and while servicing
your sandblaster!
2. Select the appropriate abrasive for your sandblaster. Refer to Page 12 for types.
3. Install the correct nozzle into the arbor for
the abrasive type hose size, air pressure
and CFM you will use. Refer to Page 12 for
options.
4. Move the tank air supply lever to the OFF or
closed position (see Figure 8).

5. Move the blast hose air supply lever to the
OFF or the closed position (see Figure 9).
Figure 9. Blast hose air supply valve, closed.
8. Remove the filler cap, insert the funnel, and
carefully—without causing a hazardous dust
cloud—pour or spade-in the abrasive into the
sandblaster. Use only enough abrasive for
your project.

Note:If you fill the tank to
⁄4 full, and the local
humidity is 90-100%, the water trap will not
be able to trap all of the moisture from the
compressed air. So you must reduce the load
of abrasive and fill the tank more often and
empty the water trap more often. Otherwise,
the sand will clog in the tank outlet and in the
blast hose.
9. Brush sand away from the sealing cap and
O-ring, and close the filler cap.
6. Point the blast nozzle in a safe direction, and
slowly move the blast nozzle lever to the ON
or open position to exhaust any air from the
tank (see Figure 10).
7. Make sure the air pressure gauge reads zero
(see Figure 10).
Figure 10. Tank air pressure at zero PSI.
10. Close the blast nozzle lever, and turn the compressor on (see Figure 11).
Figure 11. Blast nozzle valve, closed.
11. Adjust the air supply line regulator to an air
pressure between 65-125 PSI, depending on
your requirements.
Model T27158 (Mfd. Since 12/14)
12. Move the tank air supply lever to ON or the
open position (Figure 12), and the tank will
pressurize to your regulated air pressure
indicated by the tank gauge.
Note: If the tank relief valve trips open and
exhausts air, immediately turn the compressor
off and correct the over-pressurization
problem with the compressor. If the tank
exceeds its rated pressure, it may explode,
causing severe injury or death.

13. Move the blast nozzle air supply lever to ON or the open position (see Figure 13).
NOTICE
Only sandblast with the blast nozzle valve
in the fully OPEN position. Sandblasting
with a partially open blast nozzle valve can
lead to premature wear and cause machine
damage.
15. Point the blast nozzle at the workpiece and slowly move the blast nozzle valve (Figure
15) to the ON or open position. Sand blasting
will begin.
Figure 13. Blast nozzle air supply valve, opened.
14. Move the sand metering valve lever to your
required sand flow volume requirement (see
Figure 14).
Figure 14. Sand metering valve in the full-open
position.
Figure 15. Blast nozzle valve, open.
16. Move the blast nozzle in a slow circular
motion.
Note: A good starting point for tip distance is
four inches away from the workpiece. Start
out with a low air pressure setting to avoid
excess peening and abrasive wear.
Note: Experiment with different pressures,
abrasives, sand flow, and tips to gain practical
experience.
Note: Keep the sandblasting abrasives
moisture-free; otherwise, the sand elbow and
the sand flow valve at the bottom of the tank
will clog frequently.
17. When sandblasting is complete, ALWAYS
close the air supply lever before you disconnect
the air supply line. Otherwise the residual air
in the tank will expel sand backwards through
the water separator and out of the air supply
fitting, damaging the water separator.
Some common blasting abrasives are listed
below. All abrasives have benefits and drawbacks
such as quality of surface finish, abrasive life,
toxicity, and what precautions you must take to
prevent environmental damage or personal injury
to your respiratory system.
Steel Type Abrasives
This aggressive abrasive creates a rough finish
that accepts paint well. The abrasive is very durable and has a long life; however, it MUST be kept
very dry to prevent rusting.
Alumina Type Abrasives
This multi-purpose abrasive creates a smoother
finish than the steel abrasives, but has a shorter life span. Less of the workpiece surface is
removed with this more forgiving abrasive.

Glass and Garnet Type Abrasives
Typically this abrasive works well for soft metals
and addressing surface issues with equipment
parts where tolerances cannot be affected. The
life of this abrasive is limited and not well suited
for repetitive recycling.
Sand Type Abrasives
This abrasive is easy to find and gives an average
finish that is acceptable for most projects. Sand
