WOODWAY MERCURY – PATH – PRO - PRO XL 

Cleaning and Inspection

CAUTION: Turn off treadmill and disconnect power cord before cleaning. 

Weekly:

# Clean handrail, front display panel, cosmetic covers & running belt.

 Inspect power cord. (make sure all prongs are present & cord is not frayed or cut)

# Check overall condition of the treadmill. Replace Necessary part.

# Move, and vacuum underneath the treadmill.

# Check magnet assembly. (magnet, lanyard & clip)

# Ensure the red emergency stop button is functioning correctly. (*ELG treadmill)
Every Six (6) Months:

# Vacuum inside the treadmill (unplug and remove cosmetic covers)

# Inspect all nuts and bolts. Tighten or replace as needed.

# Clean running surface with a diluted cleaner such as 409 or Fantastic. Ratio 50/50.

# Check drive belt – replace if teeth are missing or shredded.

# Inspect running belt (tighten all slat screws & check belt tension)

# Inspect the set screws on shaft bearings

# Check calibrations
Yearly:

# Grease bearings on front idler shaft & rear drive shaft.

# Grease rear drive shaft pulleys

# Grease elevation racks & chains

# Remove 2 belt slats to clean bearing rails & the inside of the running belt

Seasonally:

In autumn & winter remember that the dry climate in many regions of the country will cause a greater static discharge to occur when the treadmill is used. Be sure to spray the running surface with a staticide spray regularly to prevent static shock to the treadmill users and to prevent interference with the treadmill’s electronic systems.

Lubrication

 Lubrication: Black or White lithium grease is recommended
Bearings 

Almost all of the bearings used in the treadmill are pre-lubricated and do not need to be greased. On a yearly basis, the four (4) bearings located at the front and rear shaft will need to be lubricated. One pump of grease can be inserted into the zirk fittings on the bearings. A grease gun with a flex bit will be needed for this portion. The bolts that secure the bearings to the frame need to be tightened if necessary. The set screws on the bearing collars need to be tightened and should have red loctite on them to ensure they stay tight. All set screw torque settings need to be at 78 in lbs. The ELG torque setting for the set screws needs to be 273 in lbs.

Running Belt

The teeth on the bottom of the running belt are pre-lubricated to aid in reducing noise. There is no need to lubricate the teeth. If running belt is rubbing against the side of the drive pulleys, then a small amount of grease (i.e. Molykote or equal) on the edges of the belt slats will help reduce noise. Apply grease to the teeth on the back drive shaft to help the belt stay aligned properly.

Running Shaft Assembly

The rear drive shaft pulleys should be greased once a year. A bead of grease can be applied to each set of teeth. Use sparingly. Inspect the teeth for any damage. If the teeth are damaged, the drive shaft assembly will need to be replaced as the running belt will not stay aligned or tensioned correctly.
Drive Belt

As in the case of the running belt, the application of grease on the edge of the drive belt is only needed to reduce belt squeak and should be used sparingly. The drive belt is a cogged tooth belt and may stretch; tighten if necessary. Inspect drive belt to make sure all teeth are present. Replace drive belt if teeth are missing or if belt is shredding.

Incline System

The incline systems on WOODWAY treadmills are greased at the factory. If utilized for many hours or in a very dusty environment, system will need to be checked. If needed, a small amount of grease can be applied to the elevation racks and also applied to the elevation chains. Do not use too much grease. Make sure the hardware that holds the elevation blocks to the racks is secure and tight.

Note: Use a minimal amount of lubrication to prevent excess dirt and debris from sticking to the machine after cleaning.
Adjustments and Calibration
Incline System

The Rack and Pinion style incline system is used in WOODWAY treadmills. The 15% & 25% incline systems use similar components and only differ in rack travel.
Bearing Rails

Remove 2 running belt slats to access the bearing rail assemblies. Clean the bearing rails and replace any bearing that is causing a noise issue or that does not spin freely.
Running Belt

The running belt should not require adjustment. However, if the running belt or associated parts have been changed, then belt tension should be checked and set at 8.5 for Mercury and Desmo models and 8.25 for Path and Wide Path treadmills.
Handrails 

Inspect/tighten all hardware. Replace any hardware that is stripped or missing. Inspect the handrail clamps for cracking.
Treadmill Mounting Feet

TOOLS NEEDED: 2 FT LEVEL, ¾ INCH WRENCH If treadmill wobbles or seems unstable, mounting feet must be checked. Using the level, check both ends of the treadmill. Loosen the tensioning nut and turn the foot until it is at the correct level. Tighten the tensioning nut.

ELG with Gantry

Inspect/tighten all hardware on gantry. Replace any hardware that is stripped or missing. Inspect safety harness system.
Note: When moving the treadmill the frame may flex. If treadmill seems unstable, push
handrail to one side or the other. If treadmill is still unstable check mounting feet for
adjustment.

Troubleshooting
1. No Display:

If the treadmill’s display does not light up when powered on, check the following items:

# Input power fuse – replace if blown

# Power coming out of wall outlet

# Check power with another piece of equipment (radio, fan, etc.). Check main fuse or circuit breaker, move to another outlet.

# Is the treadmill plugged in?

# Is the safety magnet installed or positioned correctly? Try to reposition. Check all connectors at circuit boards.
2. Belt Movement

# Is the safety magnet on?

# Is the display working properly?

# If the display works, and/or the incline works, unplug the treadmill and wait at least 60 seconds before plugging it back in.

BELT TIGHT/HARD TO PUSH

First, determine if display board is illuminated and/or if the incline system is working. This information will help our service technician in advising you where the source of the problem may be.

BELT BINDING

 Check for obstructions and remove if possible.

3. Incline Does Not Work

# Check for any noises from the incline motor (brake sticking/motor stalled)

# Check if incline limit switches are tripped.

# Check for broken chain, or if chain has jumped off of any sprockets.

# Check if the potentiometer is adjusted correctly.
4. Erratic or Blinking Display

# Probable causes: Low line voltage; too much load on the same line.

# Make sure treadmill is on a dedicated electrical circuit.

3 Display power supply on Interface board is defective.
5. Squeaking Sounds: 

Possible causes:

# Noisy bearing . Try greasing or replacing the bearing.

#  Drive belt rubbing against the drive pulley, try greasing the edge of the drive belt with a little all-purpose grease.

# Running belt rubbing against drive pulleys, try lightly greasing the teeth on the drive shaft, and let the treadmill run at a slow speed for a couple of minutes to spread grease evenly. (NOTE: Too much grease will make a mess and will accumulate dust).
# Check for a defective guide roller or Z roller bearing on the bearing rail, replace if defective.
