Sling Bar
Your Denali Power-Driven Mobile Lift is designed for transferring and repositioning patients by utilizing a
sling or other assistive device.
• Low clearance for greater bed or stretcher access.
• Adjustable leg width for easy access to wheelchair or commode.
• Sling bar safety pad.
• Multi-directional power drive for easy mobility.
The Denali is a mobile patient lift for people with impaired mobility. Used in conjunction with the proper sling
or other assistive device, the Denali will transfer or reposition a patient with comfort and convenience.
The Denali has a compact footprint and multi-directional drive system, allowing for greater maneuverability in
tight spaces.
Intended for use in acute care, long-term care, outpatient care, and home care. It is not
recommended for use in a shower or other wet environment.
Prior to using the Denali for transfer or any other procedure, the patient must be assessed
by a qualified professional to determine the suitability of using the Denali with that patient.
Cables must be fixed to the application or placed in such a way that users cannot stumble
and injure themselves.

SAFETY CONSIDERATIONS FOR ALL PROCEDURES:
1. The Denali is designed to be used for lifting ONLY on level surfaces and driven on NO MORE THAN a 10
degree incline.
2. Inspect the lift functions prior to any patient use. Ensure all functions are in proper working order.
3. Prior to using the Denali for transfer, the patient must be assessed by a qualified professional to determine
the suitability of using the Denali with that patient.
4. Never leave the patient unattended while in the Denali, or during any portion of the lift procedure.
5. Ensure the patient sling is used according to the sling IFU.
6. Never move the lift using anything except the driving function or manually with the handlebars.
7. Never exceed the safe working load. SWL is 600 lbs.
8. Do not power wash the Denali.
9. When cleaning and disinfecting, use a 5% chlorine bleach dilution and an EPA registered Hard Surface
Disinfectant on painted and plastic surfaces. On all other surfaces, use an EPA registered Hard Surface
disinfectant wipe that does not contain sodium hypochlorite (bleach).
10. Warranty applies only if repairs or alterations are performed by an authorized technician.
PRIOR TO FIRST USE:
The battery will be fully charged prior to shipment to the user. Charging time is 10 hours
for a full charge and 2 hours for a quick charge. In order to prolong the lifetime of the
battery, ensure that it is charged as frequently as possible.
The duty cycle on the product label must always be noted otherwise there is a risk of
damaging the lift. Exceeding the duty cycle will result in a dramatic reduction of the
lifetime of the lift. Duty cycle for lifting functions is 15% - 85% (run 2 min – off 18 min).
Duty cycle for driving functions is 50% - 50% (run 10 min – off 10 min).
If any individual parts are suspected to be damaged, do not use them.

ELECTRONICS:
BATTERY CARE AND CAUTIONS:
Handle batteries carefully.
Battery packs may emit hydrogen gas. Do not bring fire or a heated object close to the battery
pack, and never use the battery near a spark, fuses and/or equipment that emits sparks. Further,
do not store the battery in a closed environment or incorporate it into a closed structure of an
enclosure. Doing so may cause an explosion, fire, equipment damage, and bodily injury.
STANDBY MODE
When the BAJL Li-Ion is not being used for a longer period - more than a week - or when it is on
stock, it enters into a standby mode to save power and protect the battery from deep discharge.
• Connect the charger for approx. 15 seconds to exit the standby mode before use.
• There is no audio signal to indicate the standby mode or to indicate exit of standby mode.
AFTER EXIT OF THE STANDBY MODE
If there is still no power on, the battery needs to be charged.
After charging, the hand control and/or the control box will indicate the battery capacity level
again.
DEEP DISCHARGE PROTECTION
The BAJL Li-Ion has a deep discharge protection to extend the battery life.
The deep discharge protection is activated when the battery is discharged.
• Connect the charger for approx. 15 seconds to exit the deep discharge mode before use.
If the battery is completely discharged, the charging will be started at a very small rate to protect
the battery. This small charging rate is not sufficient to turn on the light in the charger, and
therefore the user may believe the system has not yet started.
Depending on the battery state, it may take several hours to get to the normal charging state. The
orange light of the control box will not be turned on as the operation is analogue. It is therefore
not possible to see the charging has started, however, only at a low level.
Do not connect the positive terminal and the negative terminal of the battery packs with a wire or
other metals.
Short-circuiting the terminals of the battery can cause burn injuries, damage to the storage
battery or trigger explosions.
Never connect the battery packs directly to a power supply socket or an automobile’s cigarette
lighter without using a charger as a medium.
Connecting the battery directly can cause the battery to leak fluid, generate heat, explode, cause
fires, or bodily burns and injuries.

Battery packs contain dilute sulphuric acid, which is a toxic substance. If battery fluid leakage
were to occur and make contact with skin or clothing, wash completely with clean water.
Additionally, if the fluid gets in your eyes, wash them with clean water immediately, and see
a doctor. When dilute sulphuric acid enters the eye, it can cause a loss of eyesight and skin
exposure can cause a burn on your skin.
Do not use or store LINAK battery packs where the surrounding temperature exceeds 50°C,
such as inside a hot automobile, in direct sunlight, or in front of a stove or a source of intense
heat. Doing so can shorten battery life, lower its performance level, cause the battery to leak
fluid, become damaged, or deform.
