PAGE 18 — WSC55 SERIES CHEMICAL SPRAY CART • OPERATION AND PARTS MANUAL — REV. #1 (08/30/19)
GENERAL INFORMATION
INTENDED USE
Operate this equipment only in accordance with the
manufacturer's instructions. Any deviation from the
manufacturer's intended use is strongly discouraged, and
the risk of such use remains entirely with the user. The
manufacturer cannot be held liable for damages incurred
as a result of misuse.
FAMILIARIZATION
Safety instructions are found on the spray cart and
throughout this manual.
Read all safety instructions
carefully
. Maintain all safety information in readable
condition. Operators should be well-trained on operation
and maintenance of the unit.
The WSC55 chemical spray cart is designed for the easy
dispersion of liquid chemicals in a variety of construction
and maintenance applications. The chemical platform holds
one 55-gallon (208-liter) drum (not included) or up to four
5-gallon (18.9-liter) buckets (not included). The platform's
sloped design allows all material inside the drum or buckets
to enter the suction tube, eliminating the waste of costly
chemical products.
Walk around the spray cart and observe each of the major
components (Figure 6)—engine, compressor, pump, hoses,
spray gun, etc. Familiarize yourself with each component
and its function before operating the unit.
Engine
The WSC55 chemical spray system is powered by a
Honda GX160 air-cooled, 4-stroke, 4.8-hp, gasoline engine
(Figure 10). For basic engine maintenance, refer to the
Maintenance
section of this manual. For more detailed
engine maintenance, refer to the Honda engine owner’s
manual.
Compressor
An engine-driven, onboard air compressor is provided
for clearing any remaining liquid from the spray system
after use. Unused liquid remaining in the hoses can
be cycled back into the drum or buckets, reducing
waste and maintenance. Refer to the
Specifications
,
Components (Compressor)
,
and
Operation
sections of
this manual for more information about the compressor.
Pump and Hoses
A cast-iron, four-roller pump delivers liquid to the spray
assembly from the user-supplied drum or buckets. The
pump is equipped with permanently lubricated bearings
that do not require further lubrication.
A 50-foot (15-meter) hose is provided with the spray cart.
However, the hose wrap will accommodate a 3/8-inch hose
up to 300 feet (91 meters) long. The spray gun, tubes, and
hoses are all equipped with quick-connect fittings for fast
and easy coupling.
Control Levers
Dual control levers are provided for operation of the pump
and compressor. The right lever engages the pump, and the
left lever engages the compressor. Refer to the
Operation
section of this manual for more information.
Maneuverability
A single rear wheel and gripped control handles provide
easy steering and maneuverability of the spray cart, and
a parking brake secures the unit on unstable or uneven
ground. Forklift pockets and a crane hook are provided for
lifting the unit, and a tow hitch allows easy transportation
of the unit around the jobsite.
Options
The chemical spray system is available as a stationary
barrel mount option (Model WSC55BM). A compressor is
not provided with the barrel mount. Refer to the
Options
and
Components (Barrel Mount)
sections of this manual
for more information on the barrel mount. A cart-only
option is also available (Model WSC55C). Refer to the part
numbers below when ordering either of these units.
