Operating a Student 150
1. Leg adjustment. The legs on a Student 150 can be opened for access around
armchairs and wheelchairs etc. For transferring and negotiating narrow
doorways and passages the legs should be in the closed position. The leg
opening mechanism is located at the rear of the lift and leg adjustment is
achieved by moving the leg opening handle to the left for open and the right for
closed. It is easier to make the leg adjustment when the lift is moving.
2. Castors and Braking. The Student 150 is provided with two braked castors
at the rear of the base. The brakes should only be applied when the lift is
parked. The brakes should always be released when a lifting operation is
taking place. With the brakes released the lift will be able to move to the centre
of gravity of the lift and prevent the client from swinging when completely lifted.
Swinging can prove disconcerting and uncomfortable and may even cause
injury.
3. Raising and lowering the boom. The boom is raised and lowered by
a powerful electric actuator controlled by a simple handcontrol unit. The
handcontrol has two buttons with directional arrows UP and DOWN. The
actuator will stop automatically at the limit of travel in both directions. The
handcontrol is plugged into a socket at the base of the Controller. The
handcontrol can be hooked on the mast or boom when not in use.
4. Emergency stop. The large, red emergency stop button is located on the
Controller and is activated by pressing in. This will cut all power to the Lift. It
can be reset by twisting the button clockwise and releasing.
5. Emergency raise/descent. Emergency raise/descent buttons are provided.
These are located underneath the emergency stop button. These can be
activated by pushing with a ballpoint pen tip or similar. This will raise or lower
the boom if the handcontrol fails.
Caution should be exercised when using this control as there is no automatic
cut-out of the actuator when the bottom stop is reached.
6. Batteries. The batteries are protected from deep discharge by a LOW
VOLTAGE ALARM. This will sound when the batteries need recharging and
the handcontrol is being operated. It will not sound independently of the
handcontrol being operated. DO NOT IGNORE THIS WARNING ALARM.
Complete the lifting operation and place the Lift on charge (see charging
instructions).
7. Slings. The selected sling is attached to the boom hooks, each sling is
supplied with instructions and they are reproduced in this manual. The
instructions should be followed carefully.
Use only UNIHOIST LTD slings, Standing and Transport range.
