Total Head is the sum of the suction head value plus the discharge head value. As water pumping height increases, pump output decreases. The length, type, and size of the suction and discharge hoses can also significantly affect pump output. It is important for the suction operation to be the shorter part of the total pumping action.This will decrease the priming time and improve pump performance by increasing the discharge head. Suction head is a maximum of 25 feet and discharge head should be a maximum of 81 feet.Total head can not be more than 106 feet (Figure 9, next page). Move Water Pump to Safe Operating Location For best pump performance, locate the pump on a flat, level surface as close as possible to the water to be pumped. Secure water pump to avoid tipover. Use hoses that are no longer than necessary. IMPORTANT: Direct open end of discharge hose away from home, electrical devices or anything not desired to get wet. WARNING Fuel and its vapors are extremely flammable and explosive. Fire or explosion can cause severe burns or death. WHEN OPERATING EQUIPMENT • This water pump is not for use in mobile equipment or marine applications. • DO NOT tip engine or equipment at angle which causes fuel to spill. • Secure water pump. Loads from hoses may cause tipover. 11 OPERATION 12 Prime the Water Pump 1. Remove plug from top of pump (Figure 10). 2. Fill pump with clean, clear water up to top of discharge outlet (Figure 10). 3. Replace pump plug. Locate Strainer Basket Into Water Source Place strainer basket into water to be pumped. Basket must be fully immersed in water (Figure 11). • NEVER operate pump without strainer connected to end of suction hose. • Keep strainer out of sand or silt, place in bucket or on stones. • DO NOT let pump run dry or damage to seals may result. Improper treatment of water pump can damage it and shorten its life. CAUTION Figure 11 — Place Strainer Basket into Water • Be sure pump chamber is filled with water before starting the engine. NEVER run pump without priming. Improper treatment of water pump can damage it and shorten its life. CAUTION Figure 10 — Prime the Water Pump Typical Water Pump Shown Figure 9 — Head Typical Water Pump Shown Discharge Head - 81 feet (25m) Maximum Suction Head - 25 feet (8m) Maximum Total Head - 106 feet (32m) Maximum OPERATION Starting the Water Pump Use the following start instructions: 1. Make sure unit is on a flat, level surface and pump chamber is primed. 2. Turn white fuel valve to “On” position (Figure 12).The fuel valve handle will be vertical (pointing toward the ground). Figure 12 — Fuel Valve Fuel Valve is shown in “On” position 3. Push on/off switch to “On” position (Figure 13). Figure 13 — On/Off Switch and Engine Speed Lever Switch is shown in “On” position Lever is shown in “Fast” position 4.Move engine speed lever to “Fast” ( ) position (Figure 13). 5.Move choke lever to “Choke” ( ) position (Figure 14). Figure 14 — Choke Lever Choke Lever shown in “Choke” position 6. Grasp recoil handle and pull slowly until slight resistance is felt.Then pull handle rapidly to overcome compression, prevent kickback and start engine. WARNING IMPORTANT: If excessive fuel is present in the air/fuel mixture causing a “flooded” condition, move choke lever to “Run” ( ) position and pull handle repeatedly until engine starts. 7. Move choke lever to “Run” ( ) position a short distance at a time over several seconds in warm weather or minutes in cold weather. Let engine run smoothly before each change. Operate with choke in “Run” position. IMPORTANT: It may take a few minutes for water pump to begin pumping water. WARNING Running engines produce heat.Temperature of muffler and nearby areas can reach or exceed 150°F (65°C). Severe burns can occur on contact. Combustible debris, such as leaves, grass, brush, etc. can catch fire. • DO NOT touch hot surfaces and avoid hot exhaust gases. • Allow equipment to cool before touching. • The water pump must be at least 5 feet from structures having combustible walls and/or other combustible materials. • Keep at least 3 feet of clearance on all sides of water pump for adequate cooling, maintenance and servicing. • Reflective exhaust heat may damage fuel tank causing fire. • Code of Federal Regulation (CFR) Title 36 Parks, Forests, and Public Property require equipment powered by an internal combustion engine to have a spark arrester, maintained in effective working order, complying to USDA Forest service standard 5100-1C or later revision. In the State of California a spark arrester is required under section 4442 of the California Public resources code. Other states may have similar laws. Pump output is controlled by adjusting engine speed. Moving the engine speed lever in the “Fast” direction will increase pump output, and moving the engine speed lever in the “Slow” direction will decrease pump output. Rapid retraction of starter cord (kickback) will pull hand and arm toward engine faster than you can let go. Bro...
