Fitting
Please note the belt tensioner
stud that is to fit into the cut-
ting arm.
Wet system
The wet system is accessible when the belt guard has been removed.
A plastic hose directs the water up to the nozzle which distributes the water
towards both cutting blades. Also note the water filter at the hose coupling
that is common to all K760 machines, see page 51.
Flow control
The flow control limits the amount of water to the cutting blades. Too much
water will cause the drive belt to slip. The flow control is pressed into the hose
just below the water valve.
The flow control consists of a rubber cylinder with a hole for water passage.
The hole varies in size according to how much pressure the flat surface on the
pressure side is exposed to, and restricts the flow to around 1–1.5 litre/min.
Service
If no water passes through the hose, this may be due to the filter being defective
at the water connection and that dirt has blocked the flow control.
This is checked and corrected by detaching the hose at the water valve. Pull
out the filter at the hose connection and check it. Gently blow compressed air
through the hose in the direction from the water valve towards the hose coup-
ling.
The flow control cannot be detached from the hose and must be replaced
with a complete hose unit.
Belt replacement
Dismantle the cutting arm
Loosen the belt and remove both nuts
holding the cutting arm.
Remove the rear belt guard that sits

you can lift the belt over the clutch
drum. Pull the cutting arm out through
the splash guard.
Separate the belt guard
Remove the six screws that hold the belt
guard together.
Lift off the blade guard and replace the
belt.

Please note the belt tensioner stud
