HYDRAULIC HOSES
Check the hydraulic hoses after every 450 hours
of operation for wear, damage, and leaks.
FOR SAFETY: When servicing machine, use
cardboard to locate leaking hydraulic fluid
under pressure.
High pressure fluid escaping from a very small
hole can almost be invisible, and can cause injury.
Contact appropriate service personnel if a leak is
discovered. Do Not operate the machine.
ATTENTION!: Only use TENNANT supplied
hydraulic hoses or equivalent rated hydraulic
hoses.
