34Figure 8Figure 7TROUBLESHOOTING (cont’d)Check the both wiring connections between the elevation motor and the power supply. Also, check the wiring harness for cuts or visualdamage.If “Err” appears in the incline display after attempting an elevation change, the control panel did not see elevation movement. Touch theincline Up or Down button and an “E 217” will appear in the Data Window. Check the wiring connection between the elevation motor andthe power supply. Check the elevation fuse to see if it has blown. If the fuse has blown, replace fuse.Hesitation of the Tread beltHesitation of the tread belt usually indicates slippage of either the tread belt (the belt you walk on) or the drive belt (the belt connecting thedrive roller to the motor). To determine which of these belts is slipping, first adjust the drive belt tension and test to see if the slippagestops. If the hesitation is not corrected than the tread belt tension needs adjustment.CAUTION: Unplug your treadmill before attempting any cleaning or maintenance.Drive Belt Tension AdjustmentStep One:Use a Phillips head screwdriver to remove the 2 screws that hold the front of themotor cover in place and remove the motor cover.Step Two: (figure 7)Locate the four motor mount screws (item 1 in fig 7) as shown in the diagramand loosen them each two turns each using the 3/16" Hex wrench.Step Three: (figure 8)Locate the drive belt adjustment screw (item 2 in fig 8) in the lowerfront end of the treadmill. Insert the Hex wrench into the drive beltadjustment screw and turn the screw 1/2 turn clockwise.Step Four: (figure 7)Complete the adjustment by tightening the four motor mountscrews (item 1 in fig 7).Step Five:Walk on the treadmill to determine if the slippage is decreased oreliminated.Step Six:If no improvement is observed, the hesitation may be caused by a loose tread belt - see "Tread belt tension adjustment" below. Ifimprovement is noticed but slippage is still present, repeat steps 2 through 5. If you tighten the drive belt adjustment screw 1 1/2 turns andthere is still hesitation (slippage) contact your authorized PaceMaster dealer. Tightening the drive belt adjustment screw more than 1 1/2turns can result in bearing damage to the motor and/or drive roller.1
