Separate 18 gallon water tank above pump panel. 2 water heaters, 12v and 120v, designed to keep water tank warm 24/7.

Question 11

Transmission Fluid Temp

Answer 11

Between 140 and 220 degrees F

Question 12

ASR

Answer 12

Anti-Slip Resistance. If one wheel is off the road, spinning, ASR will apply that brake to increase torque to the other wheel allowing it to pull the apparatus out. ASR is completely automatic.

Question 13

What to do when stuck in deep mud or snow, loose dirt, or sand

Answer 13

Press the Off Road Traction Control switch. This will allow some slippage (spinning) to assist in climbing out.

Question 18

2017 Pierce Enforcer Booster Reel

Answer 18

150’ of 1 inch hose.

Question 19

2017 Pierce Enforcer Booster Reel Friction Loss

Answer 19

30 gpm = 37 psi per 50’ section, 111 psi for 150’
