Operating Instructions; Blade Fitment - Altrad Belle GROUP RANGER 450 Manual Del Operador

• Take the Floor Saw to where it is required.
If the À oor saw is to be transported to another location, ensure that the blade is fully raised in the guard and that the engine has
been switched off. NEVER transport the À oor saw with the blade lowered or with the engine still running, even if it is only being
moved a short distance.
• Check that the water outlet valve is closed, then ¿ ll the water tank with clean water. To ensure a steady stream of water, always
make sure that the water tank water level is kept constant.
• Having carried out the checks listed in the 'pre start' section, you may start the engine.
The blade should now be spinning at idle speed. ALWAYS check the blade for any signs of wobble, vibration or unusual noise. If
any of these occur, stop the machine immediately and refer to the troubleshooting section.
• Set the throttle to maximum, use the control lever to gently lower the blade into the cut and use the depth marker to
achieve the required depth of cut.
The saw will then require gentle forward movement to achieve the cut.
The speed of travel will be determined by the condition of the surface being cut.
DO NOT stand in line with the blade and the stream of hot particles whilst sawing.
NEVER plunge the blade harshly into the cut.
If the surface to be cut is very hard, the saw will take longer to cut. Try to make more than one pass as this will reduce otherwise
excessive wear of the blade.
DO NOT try to force the saw forwards as this will cause damage to the blade.
DO NOT try to cut curves as this will cause stress cracks or fragmentation of the blade.
• To stop the Floor Saw - set the throttle to idle, raise the blade fully into the guard, let the engine idle for a couple of minutes and
then turn the engine ON/OFF switch to 'O'.
• The water spray system is designed to supply a steady stream of water to enable dust suppression whilst the machine is cutting.
This prevents clogging of the engine with dust and helps to prevent pollution of the atmosphere.

2. Open the blade guard by releasing the two clips.

plate.
8. Replace the clamping plate (2) with the dowel pin (1) passing through the
