Notes:
1. Inspect and perform maintenance periodically according to maintenance schedule.
2. The maintenance schedule relates to the normal operating conditions. If the circumstances and load condition
are adverse, shorten the interval time and perform maintenance accordingly.
3. Marked “Readjust” means the tension of the V-belt should be adjusted during the initial stage and inspected every 2,500
hours afterwards; 57-65 lbs initially, then 45-50 lbs after run-in.
