3. Safety Instructions
3.1 Avoid Personal Injury
Even though the Raizer comes tted with various safety features, never use it if persons or
animals unintendedly are close by, as this may lead to the risk of crushing. Never allow children
to play with the Raizer.
3.2 Personal safety
• To avoid personal injury, it is NOT permitted to use the lifting chair when someone or something is at
risk of being injured by crushing, cutting, falling, slipping, or similar.
• It is important that the assistant ensures that the chair can move without putting anyone or anything
at risk.
• Be extra careful when there are children and physically or mentally challenged people on or near the
chair, as these groups cannot always be expected to be able to foresee the possible consequences of
its movements.
• Never load more on the chair than the 150 kg (330.7 lbs) stated on the loading sign as the maximum
load.
• Our recommendation is to never use the lifting chair if the person is not secured with the seat-tted
safety belt.
6.4 Safety belt
• The Raizer is tted with a lap belt when delivered. The lap belt will offer safety and security and help
keep the person in position during the lift. Several safety belts can be ordered as spares.
• However, it is important to note that the lap belt will not support the torso, so additional arrangements
should be used if necessary.
6.5 Handling
The Raizer will normally be supplied by your dealer. The lifting chair is ready for use upon delivery. The
Raizer can be transported in the 2 provided bags. One is a protective cover for the seat itself. The seat is
carried in the turquoise handle.
The backrest and legs are carried in the bag by using carrying straps for hand or back (long strap for
shoulders or two straps as a backpack).
Do not subject the Raizer to severe knocks or blows as this can affect product functionality.

DHG-HEALTHCARE.COM
USER MANUAL
11
Keep the accompanying remote control dry and do not subject it to severe blows, such as by throwing it
or dropping it, etc. Cleaning may only be done using a well-wrung cloth.
Never use a high-pressure jet or running water to rinse the chair and never immerse it in
water, as this can damage the product.
4. Functionality
The Raizer is a battery-powered mobile lifting chair which raises a fallen person up to an almost standing
position in a few minutes. It can be operated by only a single assistant and requires no physical effort
from the assistant aside from a helping hand.
The lifting chair works by the assistant assembling the Raizer around the fallen person and is operated by
using the control panel on the seat or by means of the remote control. The assistant can raise the fallen
person to a sitting or almost standing position ready for relocation.
To use the Raizer, hold down the button for the entire lift. The lifting will stop if the button is released.
5. Prior to Use
Make sure that the Raizer is always fully charged. A charger and an adapter cable for USB
charging are supplied with the device, and we recommend that the Raizer always be charged
and ready for use. You should check the Raizer for power at least once every 6 months and
recharge if necessary. See also section 8.
5.1 Charging the Raizer
The Raizer must be charged for at least 6 hours prior to its rst-time use, as required and as a miniumum
every 6 months with the provided charger).
It is advisable to check the battery indicator on the side of the lifting chair to verify the level of the charger.
Charging may also be done using the USB cable; however, this takes considerably longer than with the
charger (approx. 20 hours for a full charge.
Check that the chair is charged prior to use. The battery indicator must not ash red.
The Raizer can be stored anywhere you like. However, lifting speed will be reduced if the battery
temperature falls below 0ºC. In practice, though, if charged, the Raizer will always be able to perform its
task, even if stored in a vehicle in a severe frost (-15ºC). However, you must bear in mind that components
which are either very hot or cold, may be uncomfortable to touch.
5.2 Operating the Raizer
The control panel is situated on the right side of the seat.
To turn on the Raizer, press the on/off button or the UP/DOWN arrow keys on the side of the chair. Check
that the chair is charged prior to use. The battery indicator must not ash red.

RAIZER II
DHG-HEALTHCARE.COM14
6.5 Mounting the Legs
NOTE! All 4 legs are identical and may be tted in any sequence.
Left rear leg
Insert the leg carefully, until it klicks into place. A conrmation tone will sound when the leg has been
correctly tted.
Left front leg
Insert the leg carefully, until it klicks into place. A conrmation tone will sound when the leg has been
correctly tted.
Right rear leg
Insert the leg carefully, until it klicks into place. A conrmation tone will sound when the leg has been
correctly tted.
Right front leg
Insert the leg carefully, until it klicks into place. A double conrmation tone will sound when the last
leg has been correctly tted.
Ready signal
When all 4 legs have been tted correctly, a double conrmation tone will follow.
The double alert signies that the Raizer is ready to lift a person.
The LED light on the side of the Raizer now changes from yellow to green to demonstrate that the
Raizer is ready for operation.
6.6 Headrest
We recommend supporting the neck and head of the person to be lifted as it may be hard to keep
the head upright during the lift. In most cases, in connection with the Raizer II lifting chair, we
recommend that the helper supports the person’s neck with one hand during the lifting process while
simultaneously operating the remote control with the other hand.
However, in cases where it is necessary or practical for the helper to have both hands free, a headrest
(accessory) may be a great help.
To apply the headrest, push it under the neck of the lying person so that it slides between the two
backrests.

DHG-HEALTHCARE.COM
USER MANUAL
15
6.7 Alerts Prior to Lifting a Person
Positioning the person
Make sure that the shoulders of the person are placed suitably on the Raizer and that the arms are
crossed over the chest, as the rear legs will move downwards towards the oor as soon as the UP arrow
is pressed and may hit the person should shoulder/arms be in the way.
Rear legs
Please watch out for a potential crushing between the rear legs and the oor. Make sure to keep hands
and feet at a safe distance from the movement of the legs.
Front legs
Take care that the person’s legs are together and that feet/legs are not at risk of getting in under a front
leg when the chair is raised, as the front legs move toward the oor before the chair begins to lift the
person.
DO NOT run the chair up before you have made sure that the person’s feet, arms, hands and
other extremities will not be endangered by the movements of the lifting chair.
6.8 Lifting a Person
1. The Raizer is operated by using the control panel on the seat or by means of the remote control.
2. The remote control is placed in a pocket on the side of the seat and xed with a magnet. It is
released with a light push to the upper part of the remote control.
BE CAREFUL not to lose the remote control when releasing it from the Raizer
3. The Raizer is now ready to lift the person. Before initiating the lift, make sure that the person is ready,
and give a warning that the lift will begin.
4. Support the neck of the person with one hand or apply a headrest (accessory). Press the “UP arrow”
on the side panel or the remote control.
5. Press the UP arrow until the person has reached the requested position.
6. The Raizer will automatically stop when reaching its top position and the person is in an upright
sitting position.
NOTE:
The Raizer is safeguarded against running too high and therefore stops automatically in its top position. A
conrmation tone will sound, indicating that the Raizer has reached its top position.
NEVER push the Raizer when a person is sitting on it. The wheels of the legs are only meant to
avoid scratches to the oor in connection with the lifting procedure.
The Raizer is not designed for transport of persons.

RAIZER II
DHG-HEALTHCARE.COM16
7. Disassembly
IMPORTANT! Always run the Raizer to the horizontal position prior to disassembly (otherwise the
next assembly of the Raizer will be upset).
When the Raizer has been run into the horizontal position and is ready for disassembly, place the remote
control in its pocket at the side of the seat. If all legs are dismounted and the remote control has not been
put back into its pocket, the Raizer will begin to ‘call out’ for the remote control with a warning tone (a
vibrant tone). As soon as the remote control is in place, the warning tone will cease.
Always run the Raizer to the horizontal position (until it stops with a distinct sound), prior to disassembly
(otherwise the next assembly of the Raizer will be upset).
The Raizer is disassembled by pulling all legs (4) and backrests (2) out.
Do not forget to place the remote control in its pocket, as otherwise a vibrant warning tone will sound
when all legs have been dismounted.
When the Raizer has been disassembled, all parts are stowed away in the transport bag.
8. Charging the Raizer
The battery indicator (LED) lights green when the battery is fully charged.
The battery indicator (LED) ashes red to show that the battery capacity is below 10% and the Raizer
must be recharged.
NOTE:
The indicator only lights up when the lifting chair is turned on.
The charger socket is situated in the same place as the red stop button.
1. Remove the stop button and plug the charger cable into the socket. The plug is mounted with a
magnet and will snap into place by itself.
2. Connect the provided charger to the socket on the Raizer. Or use the provided USB cable.
NOTE: Charging with the USB cable takes considerably longer than with the charger.
The Raizer must be charged for at least 6 hours prior to its rst-time use, as required and as a
miniumum every 6 months (with the provided charger). Approx. 10-15 minutes’ charging is
sufcient for 1 lift. A full charge gives approx. 40 lifts at room temperature. The number of lifts
will be reduced at lower temperatures.

11. Service Inspections
Under normal conditions of operation, a service life of >5 years may be expected, provided that the
product is maintained in accordance with the guidelines of the producer. In addition to the general
maintenance described in section 9, we recommend routine annual inspections (+/- one month)
performed by a qualied service technician.
For models with the automatic service indicator activated, the Raizer will begin to ash a service message
when it is time for the service inspection. Also, an acoustic alarm will sound to remind you that service is
due.
In case the automatic service indicator has been deactivated, a label on the product will inform you
accordingly, and service intervals may be arranged with the local dealer at your discretion.
The dealer you have bought the Raizer from will offer this service, but if you wish to use another service
provider, you as the owner of the Raizer are responsible for ensuring that the chosen service technician is
suitably qualied in the product in question.
For safety reasons it is very important that these inspections are maintained, since lacking or
improperly performed inspections may result in personal injury.
All service inspections performed must be logged in the service logbook.
12. Spare Parts & Accessories
IMPORTANT: It is important to use only original spare parts. Replacement of parts may only be
undertaken by a qualied service technician. The use of non-original spare parts may void the
right of complaint. Furthermore, product safety may be compromised, which may pose a risk to
personal safety.
