4. Before Leaving Or Servicing Machine:
–Stop On Level Surface.
- Turn Off Machine And Remove Key.
5. When Servicing Machine:
–Avoid Moving Parts. Do Not Wear
Loose Jackets, Shirts, Or Sleeves
When Working On Machine.
–Block Machine Tires Before Jacking
Machine Up.
–Jack Machine Up At Designated
Locations Only. Block Machine Up
With Jack Stands.
–Use Hoist Or Jack Of Adequate
Capacity To Lift Machine.
–Wear Eye And Ear Protection When
Using Pressurized Air Or Water.
–Disconnect Battery Connections
Before Working On Machine.
–Avoid Contact With Battery Acid.
–Use TENNANT Supplied Or Equivalent
Replacement Parts.
WARNING: Batteries Emit Hydrogen

HARDWARE INFORMATION
The following charts state standard plated hardware tightening ranges for normal assembly applications.
Decrease the specified torque by 20% when using a thread lubricant. Do not substitute lower grade
hardware for higher grade hardware. If higher grade hardware than specified is substituted, tighten only to
the specified hardware torque value to avoid damaging the threads of the part being threaded into, as
when threading into speed nuts or weldments.
