WALT power tool has been designed to
operate over a long period of time with a minimum
of maintenance. Continuous satisfactory operation
depends upon proper tool care and regular cleaning.
• As a precaution regularly check for the following
conditions:
- leaks to the tank
- unusual noise or vibration to the running motor
Draining the tank (fig. H)
Before fitting an air hose or performing any
maintenance, or when putting the unit out of
operation, the tank must be drained.
• Take hold of the drain valve screw (17) and
slowly rotate the screw so as to gradually bleed
air from the tank.
• When the pressure is at 0.7 bar, turn the valve
into the fully open position to remove any
moisture or dirt out of the tank.
• Check whether the tank pressure gauge reads
0 bar to be sure the pressure is off the tank.
• Close the drain valve.
Checking the air filter (fig. I)
The air filter (18) must be checked on a weekly
basis. After 50 hours the air filter must be replaced.
• Remove the air filter from the pump head.
• If the element is dirty, clean it with dry air. If in
doubt, replace the filter.
• Re-fit the filter.
Checking the safety relief valve operation (fig. J)
The safety relief valve (19) must be checked on a
monthly basis.
• Ensure that the pressure is off the tank.
• Take hold of the wire ring (20) on the safety valve.
• Pull the ring a few times to ensure the plunger
moves in and out.
