4.1.
AIR SuppLY
4.1.1.
Recommended hook-up procedure is shown in fig 1.
WARNING! ensure the air supply is clean and does not exceed 80psi while operating the die grinder. 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.
4.1.2.
ensure die grinder air valve (or trigger) is in "off" position before connecting to the air supply.
4.1.3.
You will require an air pressure of 80psi, and an air flow according to specification.
IMpORTANT: drain the compressor's air tank daily. Water in the air line will damage the die grinder.
4.1.4.
Clean the compressor's air inlet filter weekly.
4.1.5.
line pressure should be increased to compensate for unusually long air hoses (over 8 metres).The minimum hose diameter should be
1/4" I.d. and fittings must have the same inside dimensions.
4.1.6.
Keep hose away from heat, oil and sharp edges. Check 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 die grinder. To overcome this, connect a leader hose
to the grinder. A quick change coupling may then be used to connect the leader hose to the air line recoil hose. See fig's 1 & 2.

6. MAINTENANCE
WARNING! disconnect die grinder from air supply before changing accessories, servicing or performing maintenance. Replace or repair
‰
damaged parts. Use genuine parts only. Unauthorised parts may be dangerous and will invalidate the warranty.
6.1.
If the air supply does not have an oiler, lubricate the air die grinder daily with a few drops of Sealey air die grinder oil dripped into the
air inlet to prolong its life.
6.2.
Clean the die grinder after use.
6.3.
loss of power or erratic action may be due to the following:
a) excessive drain on the air line. moisture or restriction in the air pipe. 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 die grinder may also reduce performance. If your model has an air strainer (located in the area of the air
inlet), remove the strainer and clean it. Flush the die grinder out with gum solvent oil or an equal mixture of SAe no 10 oil and
paraffin. Allow to dry before use.
