Risk of Unsafe Operation. Unit cycles automatically when
power is on. When servicing, you may be exposed to voltage
sources, compressed air, or moving parts. Before servicing unit unplug or
disconnect electrical supply to the air compressor, bleed tank of pressure,
and allow the air compressor to cool.
To ensure efficient operation and longer life of the air compressor, a routine mainte-
nance schedule should be prepared and followed. The above routine maintenance
schedule is geared to an air compressor in a normal working environment operating
on a daily basis. If necessary, the schedule should be modified to suit the condi-
tions under which your air compressor is used. The modifications will depend upon
the hours of operation and the working environment. Compressors in an extremely
dirty and/or hostile environment will require a greater frequency of all maintenance
checks.
NOTE: See Operation section for the location of controls.
TO CHECk SAFETY VALVE
Risk of Bursting. If the safety valve does not work properly,
over-pressurization may occur, causing air tank rupture or an
explosion.
Risk from Flying Objects. Always wear certified safety
equipment: ANSI Z87.1 eye protection (CAN/CSA Z94.3) with
side shields.
1. Before starting compressor, pull the ring on the safety valve to make
sure that the safety valve operates freely. If the valve is stuck or does not
operate smoothly, it must be replaced with the same type of valve.
