Electricity Awareness –230v Grinder –Square pin or Blue Plug
3. Your Saw will either operate on 110v, and therefore have a yellow industrial plug fitted OR
on 230v in which case it will have either a normal square 3 pin plug fitted or a blue industrial
plug fitted. Decide which voltage your machine works off.
4. If you have a 230v machine with a normal square 3 pin plug fitted or a blue industrial plug
fitted:
a. Use an RCD (Residual Current Device) to protect you against an electric shock
should the machine or cable be damaged, & plug it into the 230v socket. Press the
‘test’ button to ensure it is operating correctly and follow any instructions necessary.
b. If you do need to use an extension lead, use a suitably rated heavy duty cable, no
longer than 50 metres (160 feet) and plug it into the RCD.
c. If we have provided special instructions regarding extension cables, please follow
these.
d. If you are unsure what to use, please ring us on 01375 392333.
Blades
1. Ensure that the machine you are using is switched off before fitting or changing a blade.
2. Check the blade is correct for the machine and the material you wish to cut, and that it is
sharp and undamaged with no cracks.
3. Contact John F Hunt Hire centres on 01375 392333 should you need replacement blades,
do not try to sharpen them yourself.
4. To replace blades: remove the four bolts holding the blade in place with the Allen key
provided, fit the new pair of blades with the flat surfaces together.
5. Tighten the bolts with the Allen key, but do not over tighten.
Starting and Operating the Saw
1. Having already looked for damage and familiarised yourself with the saw and it’s on/off
switch, check that the plug on your machine matches your electrical supply as outlined
above.
2. Mark out your work area with guide lines for you to cut along.
3. Unroll cables and extension leads and lay them out straight avoiding any liquids.
4. Check that the cables will not get trapped anywhere or cause a problem with vehicles or
pedestrians.
5. Do not run the saw without the blades fitted. Check the guard is in place.
6. The optimum position for operating the saw is between your chest and waist. If you need to
use it at a higher position, organise a work platform before commencing operation.
7. Start the machine using the on/off switch and hold the saw with both hands.
8. The on/off switch and interlock will enable both intermittent and continuous use of the saw.
9. For Intermittent use (locking button off):
a) Press the locking button
b) Press the on/off control
c) Release the locking button, keeping the on/off control squeezed.
