PREVENTIVE MAINTENANCE
41442 PTO PUMP
FIG. 20
1. Suction Line Valve
2. Suction Strainer
(open)
SUCTION STRAINER:
Turn off Suction Line Valve if Tank is full of spray
solution. Remove the cap and clean the strainer
screen after every 50 hours when using liquid
chemical, or after every use when spraying
wettable powders.
IMPORTANT: Do not operate the pump dry!
Be
certain Suction Line Valve is opened when
spraying is resumed. Damage to Spray Pump
will result when operating the Sprayer with Valve
closed.
Preventative maintenance is most important to
assure long life of the Skid Sprayer. The following
maintenance procedures should be followed on a
regular basis:
It is extremely important to carefully wash and
clean the Tank after
every
use.
Not only the Tank but the Pump, Hoses, Nozzles,
Screens, Filters, and the exterior of the Sprayer
also should be cleaned.
Wash spray nozzles thoroughly with water. Blow
out orifice, clean and dry. If orifice remains
clogged, clean it with a soft bristled brush... never
use a metal object.
Check all of the nozzles frequently to spot any
inconsistencies in the spray pattern. Worn nozzle
orifices which allow a greater volume of spray
material to flow through the nozzle can cause an
expensive loss in chemical and/or turf damage.
Flush Pump After Use
One of the most common causes for faulty pump
performance is "gumming" or corrosion inside the
pump. Flush the pump and entire system with a
solution that will chemically neutralize the liquid
pumped. Mix according to the chemical
manufacturer's directions. This will dissolve most
residue remaining in the pump, leaving the inside
of the pump clean for the next use.
A
minimum
of three 50 gallon rinses usually is
required for all components of the Sprayer. The
addition of a detergent cleaner may be advisable
in the initial washing. Directions for such an
addition, if required, are included on the chemical
container.
Cleaning of the Sprayer should be accomplished
in an area where there is no potential for the
chemicals to be washed off in surface water or to
enter subsurface drainage systems.
When Sprayer is not to be used for an extended
period, refer to the STORAGE section of this
Manual for the detailed instructions to prevent
damage to the components.
BELT TENSION:

ROTATING PULLEYS AND BELTS CAN
CAUSE SERIOUS INJURY.
WARNING
Keep hands, feet and clothing clear
while engine is running.
Stop engine before attempting any belt
adjustment.
Keep Belt and Pulley free from any foreign material
which may cause slippage. If a belt slips, tighten
it.
Check the tension on a new drive Belt
frequently
during the
first day
of operation and periodically
thereafter.
After every 200 hours of operation, check the
tension of all Belts. If a Belt shows signs of cracks
or fraying, install a new Belt.
