VALVE SPRING REMOVAL
4.1.1
Select valve remover and bush to suit the valve spring seat and attach to the spring compressor (fig 1:1) using the screw and
washer provided.
4.1.2
Loosen cylinder clamp screw (fig 1:2) and connect air supply to control valve (fig 1:4).
4.1.3
Place the valve remover and bush onto the valve spring seat and then open the air control by pushing the sleeve forward, towards
the cylinder (fig 2).
4.1.4
The piston stem will move forward to contact the valve head and then the cylinder will slide back in the compressor until it reaches
the end of the travel.
4.1.5
Close the air control by sliding the sleeve rearwards and the cylinder will move forward under the force of the internal spring.
4.1.6
When the cylinder has moved forward one graduation (1cm), or two graduations if the valve has two springs, tighten clamp screw.
4.1.7
Re-opening the air control valve will now compress the spring, allowing the collets to be removed.
4.1.8
It is recommended that you use a collet remover such as:
VS165, VS1651 or VS1652 (refer to Sealey catalogue for more information).
4.1.9
Close the air control valve, the compressor and the spring can now be removed.
4.1.10
When installing the valve spring use the compressor as above to compress the spring so that the collets can be fitted.

3.1 AIR SUPPLY
Recommended hook-up is shown below.
p
WARNING!
Ensure the air supply is clean and does not exceed 116 psi while operating the compressor.
Too high an air pressure and/or unclean air will cause excessive wear, and may be dangerous, causing damage and/or personal injury.
3.1.1 Ensure that the compressors air valve (or throttle) is in the "off" position before connecting to the air supply.
3.1.2 You will require an air pressure of 8bar (116psi).
3.1.3 Drain the air tank daily. Water in the air line will damage the grinder and invalidate your warranty.
3.1.4 Clean air inlet filter weekly.
3.1.5 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.
3.1.6 Keep hose away from heat, oil and sharp edges. Check hoses for wear, and make certain that all connections are secure.
