Machine Maintenance
T
o avoid costly repairs and down-time, it is imperative to develop and practice
good maintenance procedures from the beginning. These procedures fall into
daily, weekly, monthly and quarterly increments, and are outlined below. All recom-
mended maintenance must be performed by competent service personnel.
Important: Record the date and machine hours on the maintenance log.
We have provided a maintenance log for your convenience at the end of this section.
Records of maintenance must be kept and copies may be required to be furnished to
HydraMaster before the warranty is honored. It is recommended that you affix a
copy of the log on the vehicle door near your unit for convenience and to serve as a
maintenance reminder.
