Practice Safety PRACTICE SAFETY Figure 1 Practice Safety Safety signs like you see above may at first seem shocking, but their impact is mild compared with the reality of severe personal injury. Your safety and satisfaction are of the utmost importance to us. That is why before operating the vehicle, we urge you to review the information in this manual.
Safety Details SAFETY DETAILS WARNING • This owner’s manual should be read completely before attempting to drive or service the vehicle. Failure to follow the instructions in this manual could result in property damage, severe personal injury, or death. It is important to note that some vital statements throughout this manual and on the decals affixed to the vehicle are preceded by the words DANGER, WARNING, or CAUTION.
General Warnings (Viewed from driver side of vehicle) 1. Remove negative battery cable. 2. Remove positive battery cable. Connect battery cables in reverse order. Figure 2 Battery Cable Removal GENERAL WARNINGS The following safety statements must be heeded whenever the vehicle is being operated, repaired, or serviced. See Safety Decal and Feature Identification on page 5.
General Warnings WARNING • Do not leave children unattended on vehicle. • Children requiring a child safety seat must not ride on the vehicle. Comply with state and local laws pertaining to child safety. • The driver and passenger must be restrained at all times with the seat belts provided to help prevent injury in the event of sudden braking, collision, or roll-over.
Figure 3 All-wheel Drive Warning GENERAL INFORMATION This manual includes operating procedures, maintenance, and regular servicing information for all gasoline and diesel HUV 4421-G and HUV 4421-D vehicles. All operating procedures, maintenance, and regular servicing are identical unless otherwise noted. MODEL IDENTIFICATION The serial number of each vehicle is printed on a bar code decal mounted on the frame above the brake pedal (Example: RC0601-123456) (Figure 4).
Controls and Indicators Figure 4 Serial Number CONTROLS AND INDICATORS See General Warnings on page 12. WARNING • Before allowing anyone to drive the vehicle, make sure the driver is familiar with all controls and operating procedures. • Do not tamper with the high idle speed setting on the diesel vehicle. Doing so will void the warranty, as well as damage the engine and other components, and could result in property damage, personal injury, or death due to unsafe speeds.
Controls and Indicators KEY SWITCH – GASOLINE VEHICLES The key switch (7) is mounted on the instrument panel to the right of the steering column (Figure 5). It has three positions: OFF, ON, and START. To start the vehicle, place the Forward/Reverse handle in the NEUTRAL position and turn the key to the START position, and hold it there until the engine starts.
Controls and Indicators BRAKE PEDAL The brake pedal (2) is located to the immediate left of the accelerator pedal (Figure 5 and Figure 6). To slow or stop the vehicle, press the brake pedal. PARK BRAKE The park brake pedal (3) is located to the left of the brake pedal (Figure 5 and Figure 6). To engage the park brake, first apply pressure to the brake pedal, then firmly press the park brake pedal until it latches into place.
Controls and Indicators 12-VOLT ACCESSORY OUTLET The 12-volt accessory outlet (11) is located to the right of the key switch (Figure 5 and Figure 6). It provides a constant 12VDC with the key switch in the ON or OFF position. See following NOTE. NOTE: Extended use of this accessory outlet can cause the battery to become heavily discharged.
See following WARNING. WARNING • The ROPS must be properly installed before operating the vehicle. Husqvarna strongly urges that the vehicle’s occupants be properly restrained at all times with the seat belts provided. Pregnant woman: Consult your doctor for specific recommendations. The safety belt should be worn securely and as low as possible over the hips and not on the waist.
Seat Latch and Adjustment WARNING • Do not operate the vehicle with the ROPS removed. Doing so could result in property damage, personal injury, or death. • Do not remove or modify any component of the ROPS structure. Doing so will result in voiding the ROPS certification and could weaken the ROPS, resulting in serious injury or death.
Pre-Operation and Daily Safety Checklist WARNING • Do not adjust the driver-side seat while the vehicle is in motion. To adjust the passenger-side seat Remove the seat from the vehicle. Remove the four bolts and washers from the bottom of the seat mounting plate. Align the mounting plate holes with holes in the seat to achieve the desired seat position.
