****To reduce the risk of clothing catching fire the operator should wear
wool or cotton outer garments treated with a fire retardant in preference to
man-made fibers.
1.2. LEAD PAINT WARNING!
Paint once contained lead as a traditional ingredient. Contact with the dust
from the removal of such paint is toxic and must therefore be avoided. The
following action must be taken before using the grinder on a surface that you
suspect may contain lead paint.
-
Users must determine potential hazards relating to the age of paint to be removed (modern paints do not have lead content).
-
DANGER! Keep all people and pets away from the working area. The following are particularly vulnerable to the effects of lead paint dust: Pregnant women, babies, and children.
-
We recommend personal protection by using the following safety items:
a) Paint Spray Respirator (Sealey Model no.: SSP1605)

PREPARATION
4.1. AIR SUPPLY
‰ WARNING! Ensure the air supply is clean and does not exceed 90 psi
while operating the die wrench. Too high an air pressure and unclean air will
shorten the product life due to excessive wear and may be dangerous causing
damage and/or personal injury.
4.1.1. Recommended hook-up procedure is shown in fig.1.
Ensure the wrench air valve (or trigger) is in the “off” position before
connecting to the air supply.
4.1.2. You will require air pressure of 90psi, and airflow according to
specification.
4.1.3. Drain the air tank daily. Water in the airline will damage the
wrench.
4.1.4. Clean air inlet filter weekly.
4.1.5. Line pressure should be increased to compensate for unusually long
air hoses (over 8 meters). The minimum hose diameter should be 1/4” I.D. and
fittings must have the same inside dimensions.
4.1.6. Keep the hose away from heat, oil, and sharp edges. Check the hose
for wear, and make certain that all connections are secure.
4.2. COUPLINGS.
4.2.1. Vibration may cause failure if a quick change coupling is
connected directly to the wrench. To overcome this, connect a leader hose to
the wrench. A quick change coupling may then be used to connect the leader
hose to the airline recoil hose. figs.1 & 2. 
OPERATION
‰ WARNING! Ensure that you read, understand, and apply the safety
instructions before use.
5.1. ASSEMBLY
5.1.1. To attach the grinding disc you will need the two spanners
provided, one to hold the spindle and the other to loosen/tighten the flange
nut.
5.1.2. To put on a grinding disc hold the spindle with one spanner and
with the protruding side of the disc facing down toward the spindle, screw on
the flange nut and tighten with the second spanner.

such as Sealey ATO/500 or ATO/1000, dripped into the air inlet
before use or dispensed automatically through an air system oiler, such as
Sealey model SA100L or SA2001/L.
Clean the grinder after use and change the disc when worn or damaged.
Loss of power or erratic action may be due to the following:
a) Excessive drain on the air supply. Moisture or restriction in the airline.
Incorrect size or type of hose connectors. To remedy check the air supply and
follow instructions in Section 4.
b) Grit or gum deposits in the grinder may also reduce performance. Flush the
grinder with gum solvent oil or an equal mixture of SAE
No 10 oil and kerosene. Allow drying before use.
