MAINTENANCE
Service instructions
1. Adjusting the V-belt tension
Remove belt guard. Loosen nuts situated on the motor V-belt pulley and remove outer V-belt pulley half.
Remove necessary number of shims (the removal of one shim is usually suffecient). Install the removed
shims on the outside of the V-belt pulley. (If one shim is removed, install it on the outer half of the pulley, if
two, one on the outer and one on the inner V-belt pulley half, etc.). Thus V-belt alignment is maintained.
Install spring washer in a way such that the large collar comes to lie on the motor V-belt pulley. Loosen nuts
and under continual rotation of the engine V-belt pulley tighten nuts alternately. Allow engine to run for a
short while, if necessary retighten nuts.
2. Lubricating the exciter
On delivery of the machine, the exciter is filled with oil. Change oil after every 250 hours of operation, use
0,75 l SAE 10 W 40. For this purpose place the vibration plate on level ground. Remove drain plug situated
on the outside of the vibration plate. If necessary, remove the extension plate before draining the oil. This
will avoid unwanted spillages. Correct oil level = lower edge of threaded bore.
Hydraulic control
When checking the oil level in the motor and exciter, also check oil level in the centre pole head and top up if
necessary. Top up to mark when centre pole is placed in vertical position. If there is too much oil in the centre
pole head the reverse motion is hard to engage, if the quantity of oil is insufficient the advance speed is re-
duced. We use hydraulic oil Fuchs Renolin MR 520, suitable also for low temperatures, in the hydraulic sys-
tems as standard.
Mounting instruction
1. Exciter
When disassembling exciter components, always remove eccentric weights first. When assembling, the ec-
centric weights have to be installed last of all. When installing exciter shafts mind marking of toothed gears.
Assembly of exciter shaft is correct when all eccentric weights point down while piston is at half stroke. Dur-
ing assembly of eccentric weights on exciter shaft, keep shafts blocked to avoid pinching of fingers. Mind
lefthand thread when assembling V-belt pulley. Tighten all screws with the prescribed torque, mind qualities
of screws (see screw head).
2. Hydraulic control
Bleed hydraulic system after having topped up with oil, then check oil level again (total quantity required
approx. 0,4 liters).
