APPENDIX B

1. TREADMILL LUBRICATION

Your treadmill should require little maintena nce other then periodically applying lubricant. Lubricati ng under the treadbelt will ensure superior performance and extend its life expectancy.

HOW TO CHECK TREADBELT FOR PROPER LUBRICATION

Lift one side of the treadbelt and feel the top surface of the treadboard If the surface is (slick) to the touch, th en no further lubr icati on is r equired If the surface is dry to the touch, apply one packet of lubricant

HOW TO APPLY LUBRICANT

1. Lift one side of treadbelt.

2. Pour one half of the lubricant bottle under th e center of the treadbelt on the top surface of the treadboar d

3. Walk on the treadmill at a slow speed for 3 to 5 minutes to evenly distribute lubricant.

NOTE: DO NOT over lubricate tr eadboard. Any excess lubrican t that

comes out should be wiped off.

IMPORTANT: ONLY USE HALF THE BOTTLE OF LUBRICANT PER APPLICATION LUBRICATION SCHEDULE

1. After the first 25 hour s of use (2-3 months) apply one hal f bottle of lubricant

2. Every 50 hours of use (5-8 months) apply one half bottle of lubricant

We recommend that you use: Lube-N-Walk™ Treadmill Lubrication Kit.
