SAFETY PRECAUTIONS
WARNING: Failure to read and follow all
safety warnings and all instructions may
result in electric shock, fire and serious
injury. Save all warnings and instructions for
future reference. The term "power tool" in the
warnings refers to your battery-operated
(cordless) power tool.
WORK AREA SAFETY
a) Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
b) Do not operate power tools in explosive
atmosphere, such as in the presence of
flammable liquids, gases or dust. Power
tools create sparks which may ignite the
dust or fumes.
c) Keep children and bystanders away while
operating a power tool. Distractions can
cause you to lose control.
ELECTRICAL SAFETY
a) Power tool plugs must match the outlet.
Never modify the plug in any way.
Do not use any adapter plugs with earthed
(grounded) power tools.
b) Avoid body contact with earthed or
grounded surfaces, such as pipes,
radiators, ranges and refrigerators. There is
an increased risk of electric shock if your body
is earthed or grounded.
c) Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
d) Do not abuse the cord. Never use the
cord for carrying, pulling or unplugging the
power tool. Keep cord away from heat, oil,
sharp edges or moving parts.Damaged
or entangled cords increase the risk of
electric shock.
e)If operating a power tool in a damp location
is unavoidable, use a residual current device
(RCD) protected supply. Use of an RCD
reduces the risk of electric shock.
PERSONAL SAFETY
a) Stay alert, watch what you are doing
and use common sense when operating a
powertool. Do not use a power tool while
you are tired or under the influence of drugs,
alcohol or medication.
A moment of inattention while operating
power tools may result in serious
personal injury.
b) Use personal protective equipment.Always
wear eye protection. Protective equipment
such as dust mask, non-skid safety shoes,
hard hat, or hearing protection used for
appropriate conditions will reduce personal
injuries.
c) Prevent unintentional starting. Ensure the
switch is in the off-position before con-
necting to power source and/or battery
pack, picking up or carrying the tool. Car-
rying power tools with your finger on the
switch or energising power tools that have
the switch on invites accidents.
d) Remove any adjusting key or wrench
before turning the power tool on.
A wrench or a key left attached to a rotat-
ing part of the power tool may result in
personal injury.
e) Do not overreach. Keep proper footing and
balance at all times. This enables better
control of the power tool in unexpected
situations.
f) Dress properly. Do not wear loose cloth-
ing or jewellery. Keep your hair, clothing
and gloves away from moving parts. Loose
clothes, jewellery or long hair can be
caught in moving parts.
SERVICE
a) Have your power tool serviced by a
qualified repair person using only identical
replacement parts. This will ensure that the
safety of the power tool is maintained.

INTRODUCTION AND INSTALLATION
Before using you must charge the battery (during storage it may have lost part of its load).
To do this, plug the charger into a power outlet and connect it to the battery, the battery
must be disconnected from the sprayer.
Note that the charger indicator is green when it is plugged into the power outlet, and turns
red when the battery has begun charging. When the battery is fully charged the indicator
changes from red to green. The operating temperature range of the sprayer is 33ºF to
122ºF.
Follow these steps to put together your backpack sprayer:
1. Install the wand holder onto the sprayer tank
2. Insert the battery pack in its housing, to do this you open the door at
the back of the sprayer and insert it into the correct position until the
lever lock/unlock is locked.
3. Remove the cap and, using the load filter, pour the liquid in the tank. Replace
the cap and tighten securely.
4. Place the sprayer on an elevated surface, ensure that the straps are
firmly attached to the tank and pull straps on your shoulders.
5. To start working with the model GS18AS-15 (2 speeds), determine if you
want to set the pressure to low or high.
Low speed (low pressure)
Press the button down LED light changes to green when in use
High speed (high pressure)
Press the button up LED light changes to green when in use
To turn the sprayer off set the switch to the middle position

MAINTENANCE
TANK
Clean the sprayer after each use with clean water. Empty the tank completely. Never leave
the sprayer products stored in the tank, hose or pump.
FILTERS
This machine has the following filters:
Filling tank filter
Output tank filter is located the inside the sprayer at the bottom of the tank and it can be
removed for cleaning. After cleaning, reassemble into the housing in the same way and
position.
Nozzle filter located within the spray nozzle.
Proper filter maintenance is the best guarantee for a smooth operation of your sprayer.
Clean these filters regularly and replace if damaged.
NOZZLES
The sprayer is supplied with quality nozzles. The performance of this equipment may
be diminished if using a nozzle with excessive wear or if using a nozzle not recommended.
LOW BATTERY LIGHT
The charge status indicator is located next to the speed control switch. A Green light
indicates that the state of the battery charge is adequate. When the light flashes red it
means that the battery is discharged and in a few minutes the sprayer will stop
working, requiring the battery to be charged or replaced with a charged battery
RECHARGE AND BATTERY MAINTENANCE
To recharge the battery, remove the battery from its release toggled and moving up the
battery, then connect the charger to a power outlet. Then connect the plug to the battery,
the light on the charger will change from green to red, indicating that the recharging
process has begun.
The approximate time for recharging is 4-5 hours (depending on the level of discharge of
the battery). After the battery has finished charging, remove the connector from battery
and then remove the battery charger from the power outlet.

IT IS RECOMMENDED TO RECHARGE THE BATTERY AFTER EACH WORKING DAY.
Never recharge the battery in extreme temperatures, the charging temperature range is
32ºF to 104ºF. It is normal for the charger to warm up slightly during charging (red light).
For extended periods of inactivity, you should remove the battery from the sprayer and
store at half load in a dry and stable temperature (ideal range of 41ºF to 59ºF),
Use only the charger supplied with this equipment, connected to a power socket AC
standard (1 00/240 volts, 50-60 Hz).

MOTOR & PUMP
The motor, the pump and the pressure switch are sensitive items subject to wear, they are
integrated into a single module and need preventive maintenance to extend the lifespan.
To keep the pump head in proper operating condition after each application, run the
sprayer with clean water in open circuit for a few minutes. Never leave the pump with
chemical inside over 8 hours, these products may cause clogging and cause the sprayer
to malfunction . To preserve the engine, do not put it in any kind of liquid and protect it
from moisture as far as possible.
