H37i Operating Instructions33Suspension SeatA fully adjustable suspension seat is standard onModel H37i. This seat is adjustable for back pitch,weight, lumbar support and armrest inclination.Proper adjustment for each operator is essential tosafe operation and operator comfort.Read operating instructions in full before you usethe seat.NOTE: Driver seats that have been adjusted incor-rectly have little or no vertical travel with the opera-tor in the seat. To prevent damage to the driver’sback and to the seat, the seat must be adjusted forthe driver’s weight before use and before everychange of driver. To prevent injury, no objectsshould be placed within the moving area of thedriver seat.CAUTIONTo eliminate any risk of accident, the seatsettings must be checked to ensure theyare correctly engaged before the mower isdriven.Adjustments must not be made while driving.If you make any changes to the suspensionseat (for example fitting parts which are not origi-nal GRAMMER parts) it may no longer meet thesafety standards to which it is tested. Functionsmay be impaired, threatening your safety. Forthis reason, any change in design of the seatmust be approved by GRAMMER (Seat Manufac-turer).IMPORTANT: Fasteners must be checked regu-larly for tightness. If the seat wobbles there maybe loose bolts or other faults.If you note that the seat does not function correctly(for example a defective seat suspension; improp-er curving of the lumbar support or damaged bel-lows), contact your Walker dealer immediatelyto arrange for repairs to be carried out. If you failto do so, your health may be affected and the riskof accident increased.CAUTIONBefore the tractor is used, the safety switchmust be checked for proper function. Theoperation of the switch is checked by hav-ing the operator lift off the seat with thetractor moving forward and/or the bladesengaged—this action should cause the ma-chine to stop. If a malfunction is detected,the tractor must not be driven; the safetyswitch system should be repaired or re-placed before operating the mower.CAUTIONExcept for the driver’s weight during nor-mal use, no loads must be placed on seatswith a built-in switch detecting seat occu-pation, as the vehicle may otherwise startto move by itself.For armrest inclination adjustment, the inclina-tion of the armrests can be modified by turning theadjustment knob. Refer to Figure 1.Turning the knob to the right lifts the armrest infront, turning it to the left, lowers it in front.For weight adjustment, the weight of the respec-tive driver must be set while sitting on the seat.Fold out the weight adjustment handle completely,hold it at the front and move it upwards or down-wards (10 movements from minimum to maxi-mum).Before every new movement, bring the handleback to the starting position (audible lockingsound). The driver’s weight has been set correctly,when the arrow is in the middle of the viewingwindow. Refer to Figure 2.IMPORTANT: To prevent injury to the operatorand/or damage to the seat, the setting for thedriver’s weight must be checked and adjusted asnecessary before the mower is driven.When the minimum/maximum weight adjustmenthas been reached, you will notice an empty move-ment in the handle.When you have set the weight, fold the handlecompletely into the locking position.
