Lowering the platform
• Check that there are no personnel, tools or equipment in the danger zone.
• Raise the platform 20-30mm to allow the latches to be released.
• Turn the control knob towards ‘LOWER’ and whilst holding it there, progressively operate the
‘LOWER’ lever. NOTE: Whilst the platform is being lowered, it is normal for the buzzer to be heard
if the auxiliary is in its bottom position.
Stopping the platform before the reaching the floor.
• Release the control knob and then the lever when the platform is latched.
Ensure the platforms have latched correctly if required (See above).
Stopping the platform at ground level.
• Wait for the platform to come to rest before releasing the control knob and the lever.
NOTE: If, whilst being lowered, the platform comes to rest without the latches being engaged in the ladder
slots - the lower ever has been operated ‘excessively’ causing the ram safety valve to operate. If this
happens, raise the platform for a few seconds and then recommence lowering the platform by operating the
lever more moderately, so that this problem is not repeated. If this locking occurs when the platform is at its
highest point and cannot be raised any further, remove the upper limit switch so that it does not operate.
CAUTION: WHEN THE PLATFORM COMES TO REST AT FLOOR LEVEL, THE LATCHES
SHOULD NOT ENGAGE WITH THE LADDER RACK (BEFORE THE BUTTON IS RELEASED).
WIRE ROPES THAT ARE INCORRECTLY ADJUSTED MAY ALLOW THE SAFETY SWITCHES
IN THE CROSS-MEMBERS TO OPERATE. IF THIS HAPPENS, THE WIRE ROPES MUST BE
CORRECTLY ADJUSTED BEFORE POSSIBLE TO RAISE THE PLATFORM.
RAISING THE AUXILIARY PLATFORMS (493 9031)
• Ensure that the vehicle is ‘structurally suitable’ to be lifted at the points recommended by the vehicle
manufacturer.
• Set the three way valve to ‘AUXILIARY’.
• Insert the rubber blocks between the auxiliary plate and the vehicle body. (See ‘Safety Precautions’)
• Turn the control knob towards ‘RAISE’ and hold it there until the desired height is reached.
IMPORTANT: If the motor does not operate, check that the upper limit switch has not been actuated by the
platform. Similarly the upper limit switch of the auxiliary lift prevents the platform from being raised.
LOWERING THE AUXILIARY PLATFORMS (493 9031)
• Check that there the danger zone is clear of personnel, tools and equipment.
• Check that there are no obstructions or tools are left under the auxiliary platform.
• Turn the control knob towards ‘LOWER’. Whilst holding it there, progressively operate the
‘LOWER’ lever. The lift stops 150mm from the bottom and the buzzer operates.
• Release the control knob and check that it is safe to lower the platform completely.
• Continue lowering.
‘LOWER’ CONTROL
Changing the position of the lever
After being in use for some time, the end of the ‘LOWER’ lever may start to touch the motor. In order to change
its position, ensure that the needle is locked in place on its seat, unscrew the lever a few turns then turn it to the
correct position, then re-screw and firmly tighten the lever in position.
CAUTION: CHECK THAT THERE IS CLEARANCE OF 1 TO 2 MM BETWEEN THE
UPPER END OF THE SPRING TUBE AND THE SUPPORT, WHEN THE NEEDLE IS
LOCKED ONTO ITS SEAT.
