SAFETY INSTRUCTIONS
Driving on Slopes
Driving on slopes is one of the operations where the risk is greatest that the driver will lose controlor the machine willtip over,which can result in serious injury or death. All slopes require extra caution. If you cannot reverse up a slope or if you feel unsure, do not mow the slope.
Do as follows
Remove obstacles such as stones, tree branches, etc.
Watch out for and avoid driving over furrows, holes, and bumps. On uneven terrain, the machine can tip more easily. Long grass can hide obstacles.
Mow up and down, not side-to-side.
If machine stops while going uphill, disengage blades and back down slowly.
Drive evenly and slowly. Use small movements of the steering controls.
Be extra cautious with any additional equipment, which can alter the machine’s stability.
Do not
Do not make sudden changes in speed or direction.
Do not drive the machine on terrain that slopes more than 10°.
Do not mow near verges, ditches, or banks. The machine can suddenly spin around if a wheel goes over the edge of adroporditch,orifanedgegivesway.
Do not mow wet grass. It is slippery,and the tires can lose their grip, so that the machine slides.
Avoid unnecessary turns on slopes, and if it proves necessary, turn slowly and gradually downward, if possible.
8011-634
Mow up and down, not side-to-side
8011-635
Be extra cautious when driving on slopes
Avoid starting or stopping on a slope. If the tires begin to slip, shut down the bladesand drive slowly straightdown the slope.

1. Recoil Starter Grip
IMPORTANT INFORMATION
Do not let recoil cord snap back by itself. This may damage the cord or the recoil starter assembly.
Pull the recoil starter grip slowly until you feel compression, then pull it briskly.
Normally this engine will not backfire. If you get backfires, contact your Husqvarna dealer for service.
2. Ground Speed Lever
Located in the center of the console. Controls the forward speed of the mower. Push the lever forward if you want to go faster, pull it back to go slower or pull it all the way back to the stop postion.
To begin motion, the operator must move the ground speed lever forward before disengaging the neutral lock bail.
Ground Speed Lever Stop is the adjustment screw placed on the front edge of the driver´s panel. It is used to insure ground speed lever does not over travel drive levers into reverse.

3. Motion control levers
The machine’s speed and direction are continuously variable using the two motion control levers.
When both controls are in the neutral position, the machine stands still. The controls can be locked in neutral position by the Neutral bail
By moving both controls an equal amount the machine moves in a straight line forward.
WARNING !
The machine can turn very rapidly if one steering control is moved much further than the other.
In order, for example, to turn right while moving forward, move the right control towards the handle (neutral position). The rotation of the right wheel is reduced and the machine turns to the right.

5. Operator Presence Lever
Located on the handle. 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 at 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.
One or both levers must be pressed against the handle for the engine to remain running, when the blades are engaged or neutral lock bail is not locked in drive levers.
8011-661
Operator presence lever
6. Throttle Control
The throttle control regulates the engine speed and thereby the rate of rotation of the blades, assuming the control switch for engaging the mower deck is pulled out, see Engaging the Mower Deck.
In order to increase or decrease the engine speed, the control is moved forward or backward respectively.
Avoid idling the engine for longer periods, as there is a risk of the spark plugs fouling.

7. Brake/Bypass Lever
Located at the back of the rear deck. Used to apply park brake or bypass the IZT gears for free wheel (neutral) condition.
The functions for the lever is:
1. Drive, used when operating the machine.
2. Parking, parking brake applied.
3. Bypass, used when moving the machine by hand.
8011-411
Brake/Bypass lever
Parking Brake
The parking brake on IZT machines is applied when the Brake/Bypass lever is set in position 2. The parking brake must only be used to brake a machine which is standing still. Be careful if you release the parking brake on sloping ground. The machine is heavy and can move uncontrolled, especially if the lever is set to the bypass position (3).
8. Blade Engagement Switch
In order to engage the blades, pull the knob out. The blades are disengaged when the knob is depressed.
The switch energizes the clutch for the V-belt pulley, placed on the crankshaft, to drive the blades.
