Service Safety Guidelines
WARNING: Only Precor certified servicers and technicians are permitted to ser-
vice Precor products. Personal injury can result from electrical shock and/or mech-
anical moving parts.
Review the following safety information prior to servicing the equipment. This safety inform-
ation will help to prevent personal injury or damage to the equipment while servicing the
equipment.
Safety guideline you need to know and follow:
lRead and follow all Warning notices to protect yourself from personal injury.
lRead and follow all Caution notices to prevent damage to the equipment.
lRead the owner’s manual and follow all operating instructions.
lOperate the equipment on a solid, level surface.
lVisually check the equipment before beginning service or maintenance operations. If
it is not completely assembled or is damaged in anyway, do not attempt to operate the
equipment.
lNever place liquids on any part of the equipment while performing service.
lTo prevent electrical shock, keep all electrical components away from water and
other liquids.
lDo not use accessory attachments that are not recommended by the manufacturer.
Non-OEM accessories can cause injuries.
lDo not stand or climb on the handlebars, display enclosure or cover.
lOn a self-powered unit, it will either be necessary to either equip the unit with the
optional external power supply or have an assistant pedal on the unit while voltage
measurements are being taken. Because of the danger of working on the unit while it
is in motion using the optional external power supply is strongly recommended.
lOn AMT1units when the stairarms are in motion; the generator will operate and pro-
duce potentially hazardous voltages even when the battery is disconnected.
lOn AMT units with Cardio Theater PVS2units will have external power supply and
coaxial cable routed through the bottom of the unit to the top of the display console.
Cord management must be maintained
lOn AMT units, a pinching hazard exists when the unit is operated. It is possible to ser-
iously pinch a finger. The AMT can be mechanically locked by inserting a screwdriver
through the primary sheave and frame.
