Safety Precautions
7
Please read and follow the safety precautions listed below. The operation and the
use of the Unihoist patient lift is straightforward. These basic safety precautions
will help make lifting operations easy and trouble free.
•ALWAYS carry out the risk assessment and plan your lifting operations before
commencing.
•ALWAYS carry out the DAILY CHECK LIST before using the hoist.
•ALWAYS read this manual and familiarise yourself with the operating control
and safety features of a hoist before lifting a patient.
•DO NOT use a sling unless it is recommended for use with the hoist.
•ALWAYS check the sling is suitable for the particular patient and is of the
correct size and capacity.
•NEVER use a sling which is frayed or damaged.
•ALWAYS fit the sling according to the instructions in the user manual.
•ALWAYS check the safe working load of the hoist is suitable for the weight of
the patient.
•ALWAYS carry out lifting according to the instructions in the user manual.
•NEVER disconnect or bypass a control or safety feature because is seems
easier to operate the hoist.
•NEVER force an operating or safety control. Forcing will only strain or damage
the hoist and may compromise safety.
•DO NOT lift a patient with the castor brakes on.
•DO NOT attempt to manoeuvre the hoist by pushing on the mast, boom or
patient.
•ALWAYS manoeuvre the hoist with the handle provided. It is recommended
that the hoist is pushed with the patient in front.
•ALWAYS lower the patient to the lowest comfortable position before transfers.
•DO NOT push a loaded hoist at speeds which exceed a slow walking pace.
•DO NOT push the hoist over uneven or rough ground, particularly if loaded.
•DO NOT attempt to push or pull a loaded hoist over a floor obstruction which
the castors are unable to ride over easily.
•DO NOT bump the hoist down steps; loaded or unloaded, this will damage the
castors.
•DO NOT attempt to negotiate a loaded hoist on a slope.
•ALWAYS apply the brakes when parking a hoist.
•NEVER use electric hoists in a shower.
•NEVER charge an electric hoist in a bathroom or shower room.
•YOUR hoist is for patient lifting. DO NOT use it, or allow it to be used, for any other
purpose.
•ALWAYS ensure mast locking knob is in position before lifting a patient.
•ALWAYS use the hoist on a flat and level floor.
•FOLLOW a regular charging routine to prolong the life of the battery.

Operating a Unihoist Lift
9
SF25 Iss.5 July 2012
1. Leg adjustment. The legs on a Unihoist lift 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 Unihoist lift 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
Control box 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.
This function is to be used in an
emergency only.
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. Emergency descent on actuator (2012 Models onwards). An emergency
descent handwheel is located at the top of the actuator. By turning it
clockwise, this will lower the boom if the handcontrol fails.
7. 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).

10
8. Raising and lowering the boom (hydraulic models). The raising and
lowering of the boom is achieved by a powerful hydraulic ram which is
operated by two simple controls. The release valve, which is identified by an
aluminium knurled knob, and the pump handle which is a long lever on the
side of the hydraulic unit.
To raise the boom, ensure the release valve is closed. The valve is closed by
gently turning the knurled knob fully clockwise. When closed, pump the
handle with smooth even strokes for maximum effect. The handle strokes
from an upright position through an arc of 90˚. Leave the handle in the upright
position when not in use. DO NOT force the handle beyond the upper or
lower stops. The hydraulic unit can be rotated to allow the handle to be used
from either side of the lift.
To lower the boom, turn the release valve anticlockwise. The release valve is
progressive, the more it is opened the faster the descent. This facility allows
for a "hands free" descent. If the release valve is opened a fraction (a quarter
turn) a very slow speed of descent will allow the carer to work "hands free"
while assisting or comforting the patient.
REMEMBER to close the release valve before commencing lifting operations.
The release valve only requires gentle pressure to open or close.
DO NOT apply excessive force to the release valve, either to open or close.
It is not necessary and will only damage the valve.
9. Slings. The selected sling is attached to the spreader bar hooks, each sling
is supplied with instructions and they are reproduced in this manual. The
instructions should be followed carefully.

charger will not allow the batteries to "overcharge".
4. To return the Lift to service, switch OFF the mains supply. Remove the small
plug from the socket in the control box. The Lift is now ready for use
Please pay particular attention to the following points, they will help
you avoid problems with discharged batteries.
•KEEP the batteries fully charged. Place the power pack on charge
whenever it is not in use. If it is more convenient to do so, place on charge
every night. The charger will not allow the batteries to "overcharge".
• NEVER run the batteries completely flat. As soon as the audible warning
sounds, complete the lifting operation and place the batteries on charge.
•NEVER store the power pack for long periods without regular charging
throughout the storage period.
•ALWAYS make sure the mains power to the charger is switched off before
connecting or disconnecting the power pack.
• NEVER leave the power pack plugged in to the charger with the mains power off.
•ALWAYS check Battery Charger Indicator (LCD) screen.
•WARNING: Walking away with the hoist whle the charger is still plugged into the
mains could cause the cable and the charger to short out.
•NEVER dispose of the Battery Pack in a fire as this may cause an explosion. If in doubt
