1

2017 Pierce Enforcer size compared to older quantums

4 feet shorter, wheelbase is 2 feet shorter

2

DEF Consumption

2-3% of fuel consumption

3

Engine Exhaust After Treatment System

Designed to maintain itself through periodic self-cleaning called "regeneration" or "regen"

4

Passive Regen

Can occur during normal engine operations, driving or pumping. Requires no action by driver.

5

Active Regen

Apparatus may active regen without action by driver. However, when needed, driver can assist by changing the duty cycle of the engine, i.e. switch to highway driving or pump conditions or initiate a parked regen.

6

Exhaust temps during regen.

1500 degrees F

7

Solid DEF indicator light

Between 1/4 and 1/8 full

8

Flashing DEF indicator light

Below 1/8 full

9

On the 2017 Pierce Enforcer, what does the shoreline plug do?

Charges the apparatus batteries, powers the plug in the officer's rear compartment, powers the water heater for decon use.

10

2017 Pierce Enforcer warm water decon system

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

11

Transmission Fluid Temp

Between 140 and 220 degrees F

12

ASR

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.

13

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

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

14

Activating on-spot chains

Engage when traveling 2-25 mph. Do not exceed 35 mph.

15

Front Wheel Lock

Applies air to front brakes for additional holding.

16

Minimum air in system to activate pump shift control lever

80 psi

17

2017 Pierce Enforcer priming

Air primer uses brake tanks air pressure for a venturi. No fluids or oil. Priming will start when in pump gear and shut off when primed (20 psi)

18

2017 Pierce Enforcer Booster Reel

150' of 1 inch hose.

19

2017 Pierce Enforcer Booster Reel Friction Loss

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

20

How does regen work?

The soot build-up is removed by heating the filter until the soot oxidizes and turns into carbon dioxide gas

21

Brakes on an engine

Front disc brakes, rear drum brakes

22

RSC

Roll Stability Control. Senses when impending rollover conditions occur and, if detected, intervenes in the operation of the truck by automatically reducing the vehicle speed. RSC is automatic.

23

Two exceptions to pumping in pressure control mode

Drafting and Relay pumping, to avoid conflicting governor operations resulting in oscillation and pressure spikes, only the attack engine should be in pressure mode.

24

Disengage On-Spot Chains

Speeds of 35 mph or less (20 mph is preferred)

25

Rear winch capacity of brush truck

12,000 lbs

26

On brush truck, cut off switch will kill engine when pump pressure drops below _____

60 psi

27

On brush truck, name safety feature to prevent pump damage when tank runs out of water

Power cut off switch

28

On brush truck, what is the flow rate at 100 psi?

78 gpm
