Subject: Routine Inspection and Maintenance of Equipment Seats

As an ongoing service to our customers, we the Toro Company, do our best to

keep the customer informed of safety issues as they arise.

When proper seat and seat safety operation is overlooked during routine

maintenance checks, safety of the operator and/or bystander can be

compromised. In the following pages of this bulletin areas that need to be

checked during routine maintenance are described to insure proper seat slide

and seat switch operation.

Warning: Failure to comply with this bulletin may result in personal

injury due to an inoperable seat switch, or a broken

suspension that could allow the seat to disconnect from the

traction unit.

Contact your local authorized Toro Commercial Products Distributor for additional

assistance if needed.

Commonly, service maintenance emphasis is placed on cutting units, engines,

and hydraulic systems. It can be easy to overlook routine care items such as lug

nuts, loose fasteners, seats, and other areas that may lead to safety issues. This

bulletin addresses the importance of regular seat and seat switch maintenance.

Improper seat and switch operation could cause unsafe conditions which may prevent your machine from operating correctly, or could prevent your equipment operator from being protected by that system/function. The safety interlock system is used on most machines to prevent personal injury due to unintentional operation when an operator leaves the seat. When a seat is vacant, the engine should stop if the traction pedal or implement control is engaged.
PAGE 3
Debris Removal Seats are delivered with a plastic cover for shipping protection. Sometimes a seat may not have this plastic completely removed before use, leaving excess plastic in and around the seat and switch (as shown in the picture below). This excess plastic can dislodge and get caught in the switch and cause it to become inoperative. Debris such as rags, trash, or gloves should not be left around the seat for similar reasons.
PAGE 4
Replacing broken seat components. If the seat base becomes damaged in any way, the damaged components need to be replaced, not repaired. This insures proper alignment of seat and backrest assembly. This is extremely important for proper alignment and operation of the seat switch.
PAGE 5
Broken or worn rivets The seat switch mounting bracket shown below is attached to the seat with rivets. Worn or broken rivets can cause seat switches to malfunction or become inoperable. To show the importance of performing a daily check on these areas we have listed situations were the rivet is worn or broken and the problems that could result (refer to the photographs below). Even though the bar is in contact with the roller, the seat switch engagement may be intermittent if rivets are worn or broken.
PAGE 6
Damaged Suspension Frame In some cases, seat bases like the one shown below, have experienced weld failure where the pivot shaft is welded to the side rails. There are four different places where these two components connect. These components must not be re-welded. These parts are chrome plated, the plating causes metal fatigue when welded and therefore will not hold. Should these pins break away from the side rails, the seat assembly could separate from the base (serious injury could result).
