When using an electrical appliance, basic
precautions should always be followed
including the following:
Failure to follow the warnings and instructions
may result in explosion, fire and/or serious
injury.
WARNING:
TO REDUCE THE RISK
OF FIRE, EXPLOSION, OR INJURY:
• Do not run vacuum unattended.
• Do not use without filters in place.
• Do not use to pick up f lammable or
combustible liquids, such as gasoline, or use
in areas where they may be present.
• Do not pick up anything that is burning or
smoking, such as cigarettes, matches, or hot
ashes. To reduce the risk of health hazards
from vapors or dusts, do not vacuum toxic
materials.
• Do not use or store near hazardous
materials.
• If vacuum is not working as it should, has
been dropped, damaged, left outdoors, or
dropped into water, return it to a service
center.
• Do not allow to be used as a toy. Close
attention is necessary when used by or near
children.
• Do not put any object into openings. Do not
use with any opening blocked; keep free of
dust, lint, hair, and anything that may reduce
air f low.
• Keep hair, loose clothing, fingers, and all
parts of body away from openings and
moving parts.
• Use extra care when cleaning on stairs.
• Do not handle vacuum, charger, charger
plug, or charger terminals with wet hands.
• Turn off all controls before removing the
battery pack.
• Turn off the vacuum and remove the battery
pack before connecting the hose or other
accessories.
• Prevent unintentional starting. Ensure the
switch is in the off-position before connecting
to battery pack, picking up or carrying the
vacuum. Carrying the vacuum with your
finger on the switch invites accidents.
• Disconnect the battery pack from the
vacuum before making any adjustments,
changing accessories, or storing vacuum.
Such preventive safety measures reduce the
risk of starting the vacuum accidentally.
• Recharge only with the charger specified by
the manufacturer. A charger that is suitable
for one type of battery pack may create a
risk of fire when used with another battery
pack.
• Use vacuum only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and
fire.
• When battery pack is not in use, keep it
away from other metal objects, like paper
clips, coins, keys, nails, screws or other
small metal objects that can make a
connection from one terminal to another.
Shorting the battery terminals together may
cause burns or a fire.
• Under abusive conditions, liquid may be
ejected from the battery; avoid contact. If
contact accidentally occurs, f lush with water.
If liquid contacts eyes, additionally seek
medical help. Liquid ejected from the battery
may cause irritation or burns.
• Do not use a battery pack or vacuum that is
damaged or modified. Damaged or modified
batteries may exhibit unpredictable behavior
resulting in fire, explosion or risk of injury.
• Do not expose a battery pack or vacuum
to fire or excessive temperature. Exposure
to fire or temperature above 130°C (265°F)
may cause explosion. The temperature of
Page 4
SAFETY INSTRUCTIONS & WARNINGS
130°C can be replaced by the temperature
of 265°F.
• Follow all charging instructions and do not
charge the battery pack or vacuum outside
of the temperature range specified in the
instructions. Charging improperly or at
temperatures outside of the specified range
may damage the battery and increase the
risk of fire.
• Have servicing performed by a qualified
repair person using only identical
replacement parts. This will ensure that the
safety of the product is maintained.
• Do not modify or attempt to repair the
vacuum or the battery pack except as
indicated in the instructions for use and care.
• Use only as described in this manual.
Use only manufacturer’s recommended
attachments.

IMPORTANT!
When vacuuming large
quantities of liquids, do not immerse the nozzle
completely in the liquid; leave a gap at the tip
of the nozzle opening to allow air inflow. The
machine is fitted with a float valve that stops the
suction action when the collection tank reaches
its maximum capacity. You will notice an
increase in motor speed. When this happens,
turn off the machine, disconnect from power
supply, and drain the liquid into a suitable
receptacle or drain. To continue vacuuming,
refit the power head to the collection tank.
After wet vacuuming, turn the machine off and
remove the battery. Empty the collection tank,
