MANUAL NO. 539106457 REV. IR (09/20/01)
Thank you for buying an HUSQVARNA! Before operating your new mower, read, understand
and follow the important safety instructions and the other instructions contained in this manual.
Lawnmowers and all power equipment, can be potentially dangerous if used improperly.
SAFETY REQUIRES GOOD JUDGEMENT, CAREFUL USE IN ACCORDANCE WITH
INSTRUCTIONS AND COMMON SENSE.
INTRODUCTION
This manual has been prepared for the operators of the HUSQVARNA 36" and 48" 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 drive levers on the upper handle.
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.
