Installation
Figure 2 - Air Diagram
Designed to operate on 90 PSI, lower
pressure (below 90 PSI) will reduce
performance of the tool while higher
air pressure (over 90 PSI) raises the
performance of the tool beyond its
rated capacity and could cause serious
damage to tool and user.
We recommend the installation of an in-
line filter-regulator-lubricator as close
to the tool as possible.
Pre-Operation
Maintenance
Before the tool is connected to the air
supply, clean the air hose of
accumulated dust and moisture. Before
removing a tool for service or changing
accessories, make sure the air line is
shutoff and drained of air. This will
prevent the tool from operating if the
throttle is accidentally engaged.
Lubrication
Use an air line lubricator with Mobil
Almo 525 air tool oil (model 4ZF22),
adjusted to two (2) drops per minute. If an
air line lubricator cannot be used, add
air motor oil to the inlet once a day.
The use of synthetic oils for air line
lubrication is not recommended
because of possible damage to seals,
o-rings, hose, rotor blades and
polycarbonate oiler/filter bowls.
2
Always use clean dry air.
Excessive moisture and
dirt will greatly reduce the life of any air motor.
3.
Do not exceed maximum
air pressure of 90 PSI
Avoid direct contact with moving
sanding pad to prevent pinching or
cutting of hands or other body
parts. Wear gloves to protect hands.
Air Supply and Connection
Hazards.
Shut off air supply, drain
hose of air pressure and disconnect
tool from air supply when not in
use, before changing accessories or
when making repairs.
Never direct air at yourself or
anyone else.
Whipping hoses can cause serious
injury-Always check for damaged
or loose hoses and fittings.
Do not use quick disconnect
couplings at tool. See Figure 2
for correct set-up.
Whenever universal twist couplings
are used, lock pins must be
installed.
Operation
Supply tool with 90 PSI of
clean, dry air. Higher pressure
drastically reduces tool life. Connect
tool to air line using pipe, hose and
fitting sizes shown in Figure 2.
Do not install a quick coupler
directly into the grinder throttle
handle.
Operating Hazards.
Never mount a grinding wheel on a
sander. A grinding wheel that
bursts can cause very serious injury
or death when not properly guarded.
Use only coated abrasive sanding
discs or sheets properly secured to
the backing pad provided with the
air sander.
Inspect backing pad before each
use. Do not use if cracked or
damaged.
