INTRODUCTION This manual has been prepared for the operators of the HUSQV ARNA 32", 36" commercial mowers. Read, understand, and follow the safety and operating instructions.

Always stop the engine and blades, place the traction levers in drive, and place the mower in gear when leaving unattended.

The steering system of this mower uses individual right and left traction levers on the handle bars. Squeezing the traction lever will reduce tension on the wheel drive belt eliminating power to that wheel. With the opposite wheel still under power a turn is accomplished. If the traction lever is squeezed even tighter the brake will be applied to that wheel and a tighter more abrupt turn is accomplished. LEARN HOW TO USE THESE IMPORTANT STEERING/ BRAKE CONTROLS!

As an additional safety feature, these mowers are equipped with an Operators Presence System. This is an electrical interlock safety system which is activated by depressing either one or both of the Operator Presence Levers above the handle grips. Releasing both Operators Presence Levers while mowing or transporting will break the electrical circuit and cause the engine and mower to stop. The mower will not stop immediately after releasing the O.P. levers, some travel does occur.
