Maintenance, (continued)
Both adjustment screws should be tightened 1/4 turn in a clockwise direction with a
wrench and the belt checked for slipping after each adjustment. If the belt continues to
slip, repeat this process until the belt stops slipping. Make sure to only turn the adjust-
ment screws 1/4 turn each time until the slipping stops. This will insure that you do not
over-tighten the rollers. Over-tighten the rollers may cause serious damage to the tread-
mill.
If the belt tracks too close to one side, loosen the adjustment screw on the opposite side,
turning it counterclockwise 1/4 turn. Restart the treadmill and run it at 5 mph / 8 kph
for 1 to 2 minutes to insure the belt will stay in the center. Repeat the procedure if nec-
essary.
If noises develop or malfunctions occur, contact your authorized
Diamondback fitness dealer.
