4. Lower the hammer and post cap and carefully locate the post cap onto the top of the spike plate
(taking care to see the point on the post cap locates into the triangle shaped hole on the top of the spike
plate.
5. Remove the chain connecting the post cap from off the hammer hook.
6. Whilst keeping well away from the hammer starting with small strokes hit the spike into the ground
with the hammer taking greater strokes once the spike has located correctly.
IMPORTANT!
a) AT NO STAGE ANGLE OR TILT THE POST DRIVER WHILST THE SPIKE IS IN THE GROUND! This will bend the
spike pin.
b)Ensure at all times the spike is being driven parallel with the post driver beam.
7. To remove the spike:
a)
Lower the hammer onto the post cap
b)
Hook the post cap chain to the hammer
c)
Swing the Supa Spike chain over the top of the hammer (ensuring it is located behind the flange on
top of the hammer)
d)
Raise the hammer quickly several times up and down to give hard abrupt jerks which will release
the spike from the ground.
8. Once the spike has been released from the hard ‘driven in' position it will easily lift away from out
of the spike hole by raising the hammer.
9. Lower the hammer down moving the spike point away from the spike hole.
10. Release the Supa Spike chain from over the hammer and lift the spike back into the RHS cradle on
the leg of the post driver.
