Proper Operation of the Spray Gun.
1. Squeeze the handle to begin spraying.
2. To change nozzles, use a 13/16 wrench to remove the nozzle and nozzle adapter
from the spray gun or lance extension.
3. Install the desired nozzle and nozzle adapter to the spray gun or lance extension.
IMPORTANT: ALWAYS hold the spray gun with a firm grip when spraying at
higher pressures to prevent gun from whipping. Keep good footing and balance
at all times.
NOTE: It is not unusual for the operator to be exposed to chemical while operating
the spray gun—gloves should be chemical resistant.
11. Leaving
unattended
If the sprayer must be left unattended at any time:
a) Turn off power to the sprayer.
b) Relieve system pressure by depressing the gun trigger.
c) Turn off the vehicle. Set brake or block the wheels.
12. Discontinue
use if clogged
or inoperative
If the sprayer becomes clogged or inoperative during use, discontinue use
immediately.
- DO NOT attempt to service while chemicals are in the sprayer and engine is
running.
- Return to service area to review instructions for troubleshooting before
attempting to service.
Note: A reserve, clean container capable of holding at least 55 gallons should be kept for use when the
sprayer tank needs to be emptied temporarily for repairs. It is advisable to purchase a reserve tank
suitable for chemical storage from Northern Tool and Equipment for use in these circumstances. The
container should be properly labeled as to its contents if it is used.
