•
2-button safety operation of the machine's vacuum system. Both buttons must be activated at once
either to pick up a load or to put down a load.
•
The double-circuit vacuum system of the machine is monitored by two vacuumstats which, via LED
lamps, give a signal if the vacuum is insufficient for safe lifting.
•
LED lamps show which cylinder is active.
•
Intelligent overload protection shows when the machine reaches the limits of its capacity.
Note that lifting loads at the side of the machine impairs the stability of the machine, and that these risks
are
not
monitored by the machine's overload monitoring system. Always use the outrigger when handling
loads at the side of the machine (item number 1020003).
Always exercise particular care when
handling loads at the side of the machine and, as the operator, always consider whether safety
is taken care of and ensure that the capacity of the machine is not exceeded.
Safety test (before driving or lifting)
The window robot must be safety-tested daily before use. This test must be carried out without load.
Important!
If any of the items do not pass the safety test, the machine must not be used!
•
Carry out an inspection to ensure that the mechanical parts of the window robots are not worn or
damaged to such an extent that the safety of the machine is compromised.
•
Hold the operating arm down in the normal position and drive the WinLet 350 back and forth. Move
the operating arm, without load, to the top position and try driving the machine forwards and
backwards. This should not be possible.
•
Drive the WinLet 350 towards you and depress the safety switch on the handle. The machine must
stop immediately and move away in the opposite direction.
Note!
This test must be carried out in an open space where there is no risk of your being crushed
between the window robot and any objects or walls.
•
Drive the WinLet 350 away from you and release the operating arm. The spring pressure in the
operating arm must take the operating arm to the no-load top position, after which the machine
must stop at approximately 0.5 m and the truck functions must not be usable until the operating
handle is back down in the operating position.
•
Check the window robot vacuum system for leaks:
Leak test process
Place all suction cups on a level, dry and airtight surface (e.g. a window).
Start the WinLet 350 at the on/off button and wait until the red lamps go out on the operating
panel. Now activate the vacuum by engaging both buttons on the operating panel at the same time.
Both vacuum meters now show the current vacuum in each vacuum circuit. Once a full vacuum has
been achieved in both circuits (a vacuum level of approximately 75%), turn the WinLet 350 off again
at the on/off button. Now look at both vacuum meters; the vacuum level must not drop more than
10% in the course of 5 minutes.
If the vacuum loss is greater than 10% in 5 minutes, check all hose connections and tighten any
connections as required. Check the condition of the suction plates. The seals must not show any
signs of scratches.
Driving
Forward/reverse
The speed is seamlessly adjustable, and is adjusted by turning the regulator to a greater or lesser degree.
•
Keep the operating arm in the normal position and then turn the drive direction and speed regulator
to the desired position. Release the regulator to stop the machine.
