It takes approximately 4-7 minutes to inflate your board to 15 psi (recommended). You’ll set the pump to dual to start off (pumps air when pushing and pulling) and switch to single when it gets tough.  You’ll notice the board filling but the pressure gauge won’t likely show a big change in pressure until you’re three minutes in.


  1. Unroll the board completely
  2. Attach the hose to the pump
  3. Check that the valve stem on the board is in the UP position.  Do this by pushing down slightly and turning clockwise
  4. Remove any dust, dirt or sand from around the valve
  5. Attach the hose to the valve
    • Hold onto the base of the hose and push down with enough pressure to turn it clockwise into place.  This may be tricky the first time
  6. Check that the red valve is screwed into the pump (this allows the pump to fill on on the push and pull)
  7. Start pumping!
    • At around 100 pumps your board should start looking like a board, but don’t give up, you’re only halfway. If you take is out on the water now, it’ll end up looking like your paddling a banana
    • You’ll clearly see the board inflating, but the pressure gauge may not read much pressure yet, don’t fret.
  8. When it starts to get too difficult to pull up, unscrew the red stopped on the pump, then continue to pump (the pump will only inflate on the push at this point)
  9. Keep an eye on the pressure gauge; when you get to 15 psi, remove the hose and tighten the cap over the valve
    • Don’t forget to screw cap on or you might be swimming back if your board deflates in the water. 

***If the pressure gauge isn’t reading, it takes about 225 full pumps (filling on the push AND pull) to get it to 15 psi. ***

Store the boards in a cool, dry place.  DO NOT leave it out in the sun or in a hot car for extended periods of time. If you’re going to leave your board inflated between uses, just let a little air our so it doesn’t over inflate.

Inflation Operation

It takes approximately 5-9 minutes to inflate your board to 15 psi (recommended), a little longer than if you use the manual pump, but much less effort!  Plus you’ll be able to walk away and do other things and it will automatically shut off when it reaches the set pressure.

You’ll notice the board filling but the pressure gauge won’t likely show a big change in pressure until you’re a few minutes in.

The pump has two stages, you’ll hear the difference when it switches to second stage, don’t be alarmed!

  1. Plug the pump power adapter into the car’s 12V DC socket, or to a battery with a converter
  2. Connect the end of the air hose with the air pump inflation port, and twist clockwise to tighten it (Figure 1)
  3. Connect the other end of the air hose into the air valve and twist clockwise to secure it (Figure 2)
  4. Press the air pressure toggle button [PSI/BAR] to select your preferred unit such PSI or BAR
  5. Press the [+] button or [-] button to set the pressure to 15 PSI/1 BAR
  6. Press the On/Off power switch button to start the pump

During the inflating process, you can press the [+] button or [-] button to adjust the target air pressure value. 

Pressing the On/Off power button can stop pumping manually.

During the inflating process, the screen displays the real-time air pressure. The pre-set target air pressure number will flash every 3 seconds.

Do NOT use compact AC to DC wall convertors to power the pump. Connect the pump car charger adapter directly to a car’s charger socket. Or use a well charged minimum 12V 7AH external lead acid battery with the optional 12V battery connector.

Deflation Information

Once you’ve manually removed as much air as possible from the board, you can use the electric pump to suck out the remaining air.

This step isn’t necessary but might save you some time and make the board easier to pack.

  1. Remove the hose from the inflation port
  2. Connect the end of the hose with the air pump deflation port (2)
  3. Twist clockwise to tighten it (Figure 3)
  4. Attach the other end to the board valve
  5. Press the On/Off Power Button to start the deflation until all the air inside the inflatable product is discharged.

  6. Turn off the air pump to stop the deflation.

  • Make sure the connection to the 12V DC socket is tight and didn’t fall out
  • Cool the motor and restart it
  • Check the hose for blockages or cracks
  • If the problem cannot be solved, please contact Gritty Knots Paddle Co


The slide and snap centre fin has three parts, the fin, locking piece and connector string.

Step-by-step, once the board is inflated:

  1. Clear away any sand or grit. 
  2. Start sliding the fin backward, pushing on the bottom of the fin (not shark fin looking part)through the groove
    • It should slide with a little force and be snug
    • If it doesn’t slide, there may be some sand blocking the groove, clear that away before trying again
    • Double-check that the tethered clip is snapped all the way in

It’ll take less than 5 minutes to properly deflate and roll up your board.


  1. Rinse the board off with fresh water
  2. Remove the center fin and put it in the bag
  3. Remove the cap around the valve and dry the area
  4. Time to release the air; this will be loud at first
    • Push the valve extender down slightly to let the highest amount of pressure out.  
    • Let a few little bursts of air escape for about 10 seconds
    • Push the valve extender down and turn it counter-clockwise. Air should now freely escape.
  5. Help the air escape by push down at the nose and move up to the tail section
  6. If you’re storing the board for more than a day or returning it, make sure it is dry (especially the foam deck pad) before putting it away.
  7. Leave the valve open and the cap off
  8. Start rolling the board from the nose towards the tail, with the part you stand on rolling inside
  9. Secure the rolled-up board with the black strap and pack it in the bag

Store in a dry, cool place.  Don’t leave it out in the sun or in a hot car for extended periods of time.

People use their SUP paddles backwards quite often.

The angle of the blade should be facing forward, with the sticker facing away from you.
