STORAGE 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 chemical manufacturers directions. This will dissolve most residue remaining in the pump, leaving the inside of the pump clean for the next use.
PAGE 10
BEFORE OPERATING ENGINE FILL ENGINE CRANKCASE WITH OIL: FILL FUEL TANK WITH GASOLINE: IMPORTANT! The Skid Sprayer is shipped from the factory without oil in the engines crankcase. Fuel tank capacity is approximately 4 U.S. quarts (3.8 L). 1. Position the Skid Sprayer on a level surface. 2. Clean the area around the oil fill/check plug and remove it. 2 1 3 1. 3. FIG. 1 Oil Fill/Check Plug 2. Fuel Tank Cap Oil Drain 3.
PAGE 11
ENGINE OPERATING INSTRUCTIONS BEFORE STARTING ENGINE TO BEGIN THE DAYS SPRAYER APPLICATION: 1. 2. 3. 4. Check the engine crankcase oil. Check the Air Cleaner. Check cooling air intake areas. Check the fuel tank. STARTING THE ENGINE: 1. Set the Engine Stop Switch to ON. 1 2. For a Cold Engine: Place the throttle control positions. Move the choke to the FAST control to the CHOKE position. Gradually return the choke control to the RUN position after the engine starts and warms up. See FIG. 2.
PAGE 12
ENGINE MAINTENANCE ENGINE LUBRICATION: AFTER EVERY 5 HOURS OR DAILY: IMPORTANT! AFTER THE INITIAL RUN-IN PERIOD (APPROXIMATELY 5 HOURS) AND EVERY 25 HOURS THEREAFTER. 1. Check the oil level in the engines crankcase before engine start-up, while engine is cool. Have the machine on a level surface. 1. Change the oil in the engines crankcase. Change oil while the engine is warm. Refill with new oil as recommended in the chart below. 2. Clean the area around the oil/fill check plug and remove it. 3.
PAGE 13
ENGINE MAINTENANCE (Contd) CHECK SPARK PLUG: CLEAN AIR INTAKE/COOLING AREAS: Every 50 hours of operation, clean the area around the base of the plug and check its condition. Reset the gap to .030 in. (0.76 mm) or replace with a new resistor spark plug as necessary. See FIG. 4. To insure proper cooling, make sure the screen, cooling fins and other external surfaces of the engine are kept clean at all times. Do not blast clean. Clean by scraping or wire brushing and washing with a commercial solvent.

PAGE 16
USING THE SPRAYER: OPERATION 41441 CENTRIFUGAL PUMP IMPORTANT: Check all of your equipment... make sure that all components are clean, including the Tank, Pump, Strainer, Check Valves, Hoses, Nozzles, Spray Tips and Suction Line Strainer. 1. Start the engine as instructed in the ENGINE OPERATING INSTRUCTIONS section. 2. Engage the Pump and use the Ratchet Valve to start and stop boom spray while spraying. IMPORTANT! While operating the Sprayer: Do not overlap areas that have been sprayed previously.
PAGE 17
PREVENTIVE MAINTENANCE 41441 CENTRIFUGAL PUMP Preventative maintenance is most important to assure long life of the Manual Spray System. The following maintenance procedures should be followed on a regular basis: Flush the entire spraying system as described on page 16 after each use. Failure to clean the system can result in a chemical residue which can plug the Control Valve, Hoses and/or Nozzle Tips, and seriously damage the Centrifugal Pump. Wash spray nozzles thoroughly with water.

MAINTENANCE 41441 CENTRIFUGAL PUMP CENTRIFUGAL PUMP SEAL PROBLEM TROUBLESHOOTING 18 Trouble Probable Cause Remedy 1. Cracked or broken stationary seat (Ceramic) Seal ran dry and heated up. When liquid reached seal faces it was cooler, causing thermal cracks. Check to insure seal chamber is full of liquid before starting pump. On high temperature application insure proper flushing at seal faces. 2. Carbon washer scored grooved. Dirty System. Have system cleaned and flushed. 3.
PAGE 19
MAINTENANCE 41441 CENTRIFUGAL PUMP Always flush pump with water, or neutralizing agent before servicing. Refer to the illustrated Parts List for part ordering information. Pump Housing Disassembly In most cases, seal replacement requires disassembly of only the pump half of the unit. 1. Remove the four casing cap screws with 9/16" box end wrench. Tap pump casing on discharge port with rubber hammer, if necessary, to break loose from mounting flange. Check inside of pump casing including suction port.
PAGE 20
SAFETY INSTRUCTIONS 41443 DIAPHRAGM PUMP 1. When the Diaphragm (high pressure) Pump System is to be used: A. Check hoses for weak or worn condition before each use. Make sure that all connections are tight and secure. B. Make sure there are no restrictions in the hoses serving the Diaphragm Pump. Liquids under high pressure are dangerous! WARNING Loss of control of the transport vehicle can cause serious injury to operator or bystanders.
