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.

Service Safety Guidelines

lOn treadmills, removing the hood exposes high voltage components and potentially
dangerous machinery. Exercise extreme caution when you perform maintenance pro-
cedures with the hood removed.
When servicing the equipment:
lDuring service operations you will be very close to moving machinery and voltage
bearing components:
oRemove jewelry (especially from ears and neck).
oTie up long hair.
oRemove neck ties.
oDo not wear loose clothing.

Service Safety Guidelines

General Information
The following information provides general equipment and service information that will help
you to use this manual to properly repair and maintain the treadmill.
Features
The equipment operating specifications.
Feature Specification
Console
P31 with optional PVS1(personal viewing system)
SCL800 model specific console:
The PAUSE key is replaced with a STOP key. Functions as a typ-
ical P31 PAUSE key plus as a manual emergency stair stop key.
Speed
(step rate)
Range: 20 - 165 SPM2(steps per minute)
Levels: 30 levels, 5 spm increments
Note: Numeric keypad: Can be used to set the speed to any value
between 20 - 165 spm.
StairClimber Metrics Steps/Min, Average Steps/Min, Total Steps, Floors (16 steps/-
floor), Elevation Gain, Step Rate Levels (1 - 30)
Manual Stop keys
There is a console STOP key and a handlebar Remote STOP key.
Pressing either STOP key initiates a pause and immediately slows
and stops the stairs.
Exception: Pressing the Stop key once during a workout starts the
Pause session, except for the fitness tests (WFI and CPAT),
where pressing Pause terminates the workout.
Auto Stop The stairs will stop when weight is removed from the stairs.
Drive System &
Speed Control
The drive system is comprised of a low friction, two-stage drive sys-
tem with a proven electro-mechanical EMS braking system. The
first "resistance brake" stage uses a belt drive system. The second
"stair step" drive stage uses a heavy duty 428 O-Ring motorcycle
chain drive system.
The step drive uses the weight of the user and a resistance brake
(EMS brake) to control the step speed. The minimum weight of the

Features

Feature Specification
user is rated at 90 lbs (41 kgs) and the maximum weight is 400 lbs
(181.5 kgs).
The speed of the steps is controlled by the resistance brake (EMS
brake). The resistance brake keeps the stairs from going faster
than the console target SPM.
Dismounting and Offloading
• Dismounting – the user completely takes off their weight from
the Stairclimber, and the stairs slowly come to a stop.
• Offloading – the user takes some weight off the stairs, so there
is not enough weight to maintain the speed and the stairs slow
down. Some speed can still be maintained during an offload situ-
ation. When the exerciser returns more than 90 lbs on the stairs
(reloads), the speed will return to the target SPM.
During an offload situation the SPM display will show the target
speed if the SPM is within 10 SPM of target or will show the actual
speed if it is more than 10 SPM from the target speed. If the SPM
slows to much, the machine will go into pause mode.
If the user attempts to make SPM changes during an offload con-
dition, the target SPM will be set to the actual SPM of the unit. The
user will be unable to make target SPM changes until enough
weight has been applied to the stairs for the actual and target SPM
to be within 5 SPM. If a workout has preprogrammed SPM
changes, the target SPM will continue to change.
The rate of speed change that occurs with offloading and reload-
ing will be controlled at a linear rate and not immediately returned
to the previously set target SPM.
Drive Belt Replace-
ment
The drive belt must be replaced every 39 million steps of use.
A belt replacement notification message will show prior to reach-
ing the 39 million step interval. The machine will be disabled
"out-of-service" if the drive belt has not been replaced.
Obstruction Sensor
There is an Obstruction "OBS1" sensor located at the bottom of
the stairs. There is an IR2emitter sensor on the left side and an IR
receiver sensor on the right side. When an obstruction is detected
(blocked IR beam), the workout is paused, and an
OBSTRUCTION DETECTED" message is shown. The workout
will resume when the obstruction is removed.
1Obstruction sensor.
2Infrared Radiation: Electromagnetic radiation with wavelengths longer than those of visible
light. It is therefore invisible to the human eye. IR is generally understood to encompass
wavelengths from the nominal red edge of the visible spectrum around 700 nanometers (fre-
quency 430 THz), to 1 millimeter (300 GHz).
