correct position and in perfect condition.
- As there is the continuous risk of inadvertent damage
to the electric cables, these must be checked regularly each
time before the machine is used.
Never leave the machine out in the open. Make sure that it is stored
in a sheltered area away from extreme weather conditions.
Replace worn or faulty components with original spare parts.
WARNING! If the electric motor or control panel are
removed for maintenance, it's necessary to replace the relevant
seals in order to guaranty the right degree of protection and
safety against penetration of water inside to the electric circuits.
15.1 TANK CLEANING ON WORK COMPLETION
On completion of work, empty the tank and remove. Clean
thoroughly to remove cutting residue.
15.2 TANK REMOVAL (Ref.Fig.7)
Lift the tank (ref.1) to detach from its supports (ref.2) and remove
from the side indicated by the arrow.
15.3 WORK SURFACE CLEANING
Always keep work surfaces clean. Residual dirt can impair cutting
precision.
15.4 GUIDE RAIL CLEANING
The horizontal guide elements on the carriage are protected against
dirt build-up by scrapers. However we advise thorough cleaning of
the guide rails to ensure correct operation.
WARNING! Do not use any type of lubricant on the
guide rail.
15.5 CLEANING AND MAINTENANCE OF COOLING CIRCUIT
- If water does not reach the blade stop the machine immediately to
avoid blade damage.
- After switching off the machine ensure that the water level is
sufficient.
- If necessary, after disconnecting the machine from the power
supply check that the tap, hose and pump filter are not blocked
- If necessary, check that the impeller rotates freely (after extended
periods of disuse)
- If necessary, remove the pump and check that the pump/motor
coupling is in perfect condition.
15.6 DRIVE BELT REPLACEMENT
- Disconnect the machine from the power supply
- Remove the water hose connection by loosening the hose clamp
on the blade guard.
- Remove the blade, the two flanges, the blade half-guard securing
screws, the locking knob (ref.1, chart 2) and remove the blade
external half-guard (motor side).
- Remove the blade shaft with pulley from the bearing (ref.27, drawing
02) and fit into the bearing of the half-guard previously removed
(ref.14, chart 2).
- Fit the new belt onto the two pulleys and refit the belt tensioner.
- Refit the seal on the edge of the guard and ensure that it is in good
condition and that the two locating pins are in the correct position.
- Refit the guard inserting the blade shaft into the bearing (ref.27,
chart 2) taking care to align the screw (ref.51, drawing 2) located on
the slot of the head fulcrum (ref.19, drawing 2) with the locking
handle hole (ref.1, drawing 2).
- Join the two blade half-guards using the two locating pins to align
correctly.
- Screw in the two blade half-guards by tightening diagonally opposite
screws alternately.
- Screw in and tighten the locking handle before installing the blade.
