Releasing Pressure

Releasing the pressure in your sprayer

To release pressure from the tank, turn the tank upside down, and then squeeze the flow control lever until all the air pressure is gone. If your sprayer has a pressure relief valve, turn knob clockwise until all air pressure is gone.


Locking down the pump on your Chapin Concrete sprayer (Trilock pump)

Models: 1949, 19049, 19149, 19249, 1969, 19069, 1979, 1999, 1941, 1831, 1749, 1739, 10800, 10700, 6300

1) Place the pump back in the tank.

2) Turn the handle to the right a quarter of turn to lock the two tabs into the metal locking nut. Note:  the handle must remain in the locked position.  When spinning the handle to the left, do not push the handle down.

3) Spin the handle to the left (counter clockwise) until it stops.

4) Look at the triangle piece.  If the threads are above the triangle, the pump is in the right starting position.  If the threads are below the triangle, the lock and triangle are stuck together from the powder coating process.

5) Put one hand on each side of the pump handle and force the handle to the left to free it up.  Once it starts spinning, keep turning it to the left until it stops.

6) Turn the triangle piece to the right (clockwise) and it should go under the second lip on the inside edge of the tank.

7) Spin the pump handle to the right and it should start locking down into the tank properly for you.

8) Important note:  every time you open the sprayer whether it’s to clean it, refill it etc, always make sure the spin the handle to the left until it stops or you will run into this problem again.

9) Turn the handle to the right a quarter of turn to lock the two tabs into the metal locking nut.  Note:  the handle must remain in the locked position.  When spinning the handle to the left, do not push the handle down.

1) Grab the trigger you push down to make it spray and pull it straight up and off.  It should pop right off.

2) Using a flat headed screwdriver, push the tab in each of those notches until you hear it click.

3) If you look at the top of the handle you pulled the lever off of, you should see four slots in the same shape with a knob coming up out of the middle of it.

4) Line the four prongs on the lever up into the four slots in the top of the handle.  Using the lever as a wrench, turn it to the left (counter clockwise) to unscrew the bushing until you can lift it out and set it aside.

5) If you look into the handle, you should see a little piece of rubber about the size of a nickel. 

6) Tap the handle until that little piece of rubber pops out into your hand.

7) If you look at the piece of rubber you should see a dimple.

8) Place the piece of rubber back in the handle with the dimple pointing up towards you. 

9) Place the bushing back in the handle and screw it back in being careful not to over tighten it.  Only tighten it until the threads are flush with the top of the handle.

10) Slide the end of the lever with the “U” shape under the knob on the handle and push the lever down.  It should snap right back on to the handle.

1) There are two notches, one on each side of the pump, right above the threads.

2) Using a flat headed screwdriver, push the tab in each of those notches until you hear it click.

3) Once you have pushed both the tabs in, the barrel will slide right off the handle/rod assembly giving you access to the o-ring at the bottom of the plunger rod.

Lubricate

1) Check underneath bottom valve and make sure is clean and free of debris. 

2) If the bottom valve is deformed, cracked or warped it will cause the liquid 
product to back up into the pump assembly.

3) Be sure to replace the bottom valve once you have determined it is still in good working order.

4) Next pull the pump apart by pushing the two locking tabs on either side of the pump in and up.  You will want to push those tabs in and up with a screwdriver.  Once released, pull the pump rob assembly out.

5) Now check your plunger “O” ring by pulling the “O” ring off & inspect it for cracking, splitting or warping.  If the ring looks ok then relubricate it with vaseline or grease.

6)  Slide plunger back into the pump housing, line up the two side tabs and when you hear them click that is your indication that it is now secure.

7)  Inspect pump seal that goes to the tank, if it looks ok again apply some grease or vaseline around the seal, realign the tabs with the collar slots and snap back into place.

Storing and maintaining your sprayer

▪ Store your sprayer out of direct sunlight in a cool, dry space.

▪ Before freezing weather, make sure to drain all liquid in the tank, pump, pressure cylinder, hose, shut-off valve, wand and nozzle, to avoid liquid expansion that could crack interior sprayer components.

▪ Lock the shut-off valve in the “open” position.

▪ Inspect the hose, wand, pump, tank and shut-off valve for wear, damage or leaks on a regular basis, and repair defects promptly.

▪ When service is required, call your nearest Chapin dealer and always insist on original Chapin manufactured replacement parts.
