Winterizing the Tank
- Grease the packing glands and bearings.
- Flush the inside of the tank completely with water. A pressure washer is recommended for this.
- Pump the wash down water and sealer residue out through the pump and hose into a container.
- Remove plug from the bottom of storage tank and allow any remaining water to drain out into a container. Grease the threads on the plug and replace plug immediately.
- Remove and clean the basket strainer.
- Turn pump on, with basket strainer lid opened, and flush basket strainer with clean water. Mix up to 2 gallons of antifreeze solution and flush that through basket strainer and pump.
- Remove battery and store inside
- Close manhole on top of tank to prevent rain and snow from entering tank.
Winterizing the Pump
- Remove the rear housing of the material pump.
- Pull out the lower pump gear and thoroughly wash with water.
- Rinse out the pump housing.
- Brush oil on all interior parts of the material pump including gears, housing, back plate and bolts.
- Slide rear housing plate back onto material pump. Replace bolts but do not tighten. Be sure to leave a gap between the housing plate and pump housing. This must be done to prevent pump from cracking during the winter.
Winterizing the Engine
- Remove spark plug and spray W-D 40 (or similar penetrating oil) into the cylinder and replace spark plug.
- Cover and wrap the engine with plastic or canvas to protect from weather.
Winterizing the Hydraulic Valves
- Shift forward/reverse agitator valve into position to protect the spool valve from the weather.
- Close the agitator speed control valve to protect the valve shaft from the weather.
Chipping and Cleaning the Inside of Bulk Tank
NOTE ““ Temperature should be below 32° F when chipping sealer on inside of tank. Colder temperatures will cause the dried sealer to be more brittle, making the job much easier. Please be sure to follow Lock Out/Tag Out and Confined Space Entry procedures when entering tank.
- Remove clean-out cover from the rear of the tank.
- Use an air-opened chisel with a 2-inch spade bit to remove dried sealer. Wear proper hearing protection.
- Start chipping at the top of the tank and work your way down the sides of the tank. Use a shovel to remove accumulated sealer chunks out through the clean out hole. Be sure to chip and remove the sealer from the agitator shaft and blades.
- Tighten the bolts on the pump housing plate.
- Uncover the engine and replace battery.
- Put 50 gallons of water in sealer tank and check for leaks.
- Start engine and pump water out.
