P-100 Pump - Features: P-100 Pump - Features Suction Inlet Strainer Drain Valve at bottom of pump Exhaust Ejector Primer P-100 Pump - Set up for working: P-100 Pump - Set up for working Suction hose to inlet of pump, into water Delivery hose from discharge valve If Needed - special hose from exhaust (If working inside compartment) P-100 Pump - Preparation: P-100 Pump - Preparation Check Oil Level ( Either side) Remove & wipe dipstick insert only until threads touch case add oil if needed. Check Fuel Level (Sight tube on tank) Check suction couplings tight Suction strainer into water (Support hose) Connect Discharge Hose Maximum Suction height - 22ft ! P-100 Pump - Starting: P-100 Pump - Starting Make sure drain valve is closed ! Open Fuel Valve (lever downwards) Set Black Knob of Throttle to “Start” Set decompression lever DOWN TWO HANDS on starter rope handle ONE FOOT on bar beneath engine. Good - Hard Pull using both arms ! Warning - Reverse Running: Warning - Reverse Running If not started properly - engine can run backwards. Smoke comes out Air cleaner intake. Throttle to “Stop” immediately. Turn off Fuel Push Decompressor lever DOWN P-100 Pump - Engine Running: P-100 Pump - Engine Running When engine starts - Throttle to smooth idling speed. Do not run dry for more than 1-2 mins. P-100 Pump - Priming: P-100 Pump - Priming Engine at “Full Speed” above 10ft lift Open White Air Valve (In-line with hose) Primer lever to Horizontal Position Water from primer pipe -close White air valve. Primer lever back down to vertical. Open discharge valve Adjust Throttle to desired pressue If water does not flow - Prime again. P-100 Pump - Adjust gland: P-100 Pump - Adjust gland If water sprays from shaft gland at rear of pump - adjust the sealing gland. Use 9/16 AF spanner to GENTLY screw hex head of gland plunger inwards. 15 to 20 drips/min of water should flow Do NOT overtighten or stop flow Extra pellets of packing can be added. P-100 Pump - Working: P-100 Pump - Working Adjust throttle to get desired pressure. Do not overload engine - if Black Smoke from exhaust, reduce throttle. Watch Pressure Gauge. Listen to Motor Watch Fuel level. P-100 Pump - Refuelling: P-100 Pump - Refuelling Refuel when engine is cold. (If possible) Refuelling hot engine - BE CAREFUL ! Use Funnell. Do NOT spill fuel Stand - by with Fire Extinguisher P-100 Pump - Stop Engine: P-100 Pump - Stop Engine Reduce Engine speed to “Slow Idle” Idle for 2 mins Throttle control to “Stop” If engine does not stop, turn off fuel and wait. P-100 Pump - After Use: P-100 Pump - After Use Drain Pump using small drain valve at lower pump casing. CLOSE DRAIN VALVE ! (Pump will not prime if valve is left open) Flush with Fresh Water Refuel and Check Oil Wipe Down. Inspect. Re-stow & Lash. P-100 Pump Do’s & Dont’s: P-100 Pump Do’s & Dont’s Do not run pump dry. Do not run at pressure with no flow. If Pump will not respond to Throttle:- Shut Fuel Tank Valve push decompressor lever DOWN Do not spill fuel. Do not start engine in flammable vapour P-100 Pump - Maintenance: P-100 Pump - Maintenance To Drain Fuel from Tank:- Remove drain plug from bottom of tank Drain Fuel - replace plug & tighten Fuel Filter removal & inspection Drain fuel as above Remove two nuts beside fuel tank valve. Remove Fuel Cap, Strainer, then filter. P-100 Pump - Maintenance: P-100 Pump - Maintenance Clean Engine Oil Filter at 6 months or 500 hours. Remove oil drain plug (either side) Drain Oil Loosen lock bolt on oil filter cover Remove oil filter, inspect, clean, replace. Refill with oil - SAE 10W/40 Change Oil @ first 20hrs, then each 3 mths or 100 hrs P-100 Pump - Maintenance: P-100 Pump - Maintenance Inspect Air Cleaner element @ 3months or 100 hours. Remove wing-nut, and cover Warning - Do Not Use Flammable Solvent to Clean Air Cleaner Body Wipe clean with dry cloth. Replace element if dirty. P-100 Pump, Flush Sea Water: P-100 Pump, Flush Sea Water Do not leave Salt Water inside Pump Open Drain Valve, Drain. CLOSE Drain Valve Pump Fresh water at 50 psi for 5 mins Drain, CLOSE valve Store pump. P-100 Pump- Visual Checks: Regularly check all parts of pump:- Frame Skids Carrying Handles Engine Mounts Suction Inlet, Discharge Coupling Hoses & Clamps on pump Suction & Exhaust hoses for damage Recoil Starter & Rope P-100 Pump- Visual Checks P-100 Pump- Visual Checks: P-100 Pump- Visual Checks Further Visual Checks:- Throttle movement Priming Line Valve Drain Valve Pressure Gauge Fuel Level Tube Priming Unit - Free to move open & close Air Filter Housing Engine - Oil Leaks ? Cracks or damage to castings ? P-100 Pump- Weekly Turn-Over: P-100 Pump- Weekly Turn-Over Turn Fuel Valve Off Throttle at STOP position Do NOT try to Start engine Pull Start rope slowly - feel compression Decompression lever down & HOLD Slowly pull starter handle full length. Lift decompression lever. P-100 Pump - External Lubrication: P-100 Pump - External Lubrication Put Silicon Grease on:- Throttle pivot points. Governor pivots (Move control to spread) Decompression Lever Pump Drain Valve Threads (Open/Close) Suction Inlet Threads P-100 Pump - Repacking Gland: P-100 Pump - Repacking Gland When Plunger of Gland Stuffing Box is near bottom of thread:- Remove Packing Gland Nut with Plunger Screw Plunger fully out from cylinder. Insert One Fresh Pellet of G926 Packing Replace nut and screw plunger down Adjust GENTLY with 9/16” AF spanner DO NOT USE POWER TOOL OR RATCHET P-100 Pump - After Repacking Gland: P-100 Pump - After Repacking Gland Prime Pump and flow water at 50 psi Adjust Plunger GENTLY to reduce leak About 20 drips of water per minute Maximum Pressure for 10 mins - Adjust again to 20 drips per minute Do NOT tighten dry. Gland MUST leak. Several adjustments may be necessary P-100 Pump - Summary: P-100 Pump - Summary Clean Fuel Regular Maintenance Drain Salt water, wash withFresh water. Lash down on board ship.
