Batteries: Preparation; Batteries: Installation And Connection - Tennant T290 Manuel D'instructions

5.5.1. Batteries: preparation

During installation of the batteries or any type of battery maintenance, the operator
must be provided with the necessary personal protection devices (gloves, goggles
overalls, etc) to limit the risk of accident. Keep away from naked flames, avoid short
circuiting the battery poles, avoid sparks and do not smoke.
Batteries are normally supplied filled with acid and ready for use.
If the batteries are dry, proceed as follows before installing them in the machine.
• remove the caps and fill all elements with specific sulphuric acid solution until the
plates are entirely covered (this requires at least a couple of passes for each element);
• leave for 4-5 hours to allow the air bubbles to come to the surface and the plates to
absorb the electrolyte;
• make sure the level of electrolyte is still above the plates and if necessary top up with
sulphuric acid solution;
• close the caps;
• mount the batteries on the machine (following the procedure described below).
Before starting up the machine for the first time, charge the batteries as follows.

5.5.2. Batteries: installation and connection

Check that all switches on the control panel are in the "0" (off) position.
Make sure you connect the terminals marked with a "+" to the positive poles of the
battery. Do not check the battery charge by sparking.
Meticulously follow the instructions given below as short circuiting the batteries
could cause them to explode.
•
Make sure the two tanks are empty (if necessary, empty them. See the relevant
paragraph).
•
Release the dirty water drum (fig. 2, ref. 2) from the detergent tank (fig. 2, ref. 7) by
pulling the catch (fig. 3, ref. 1).
•
Lift the dirty water drum and tilt it backwards by about 90°. This provides access to
the battery compartment (in the detergent tank) from above.
•
Place the batteries in the compartment in the direction shown in the drawing
printed inside the compartment on the detergent tank.
Mount the batteries on the machine using lifting means suitable for their weight.
The positive and negative poles have different diameters.
•
Referring to the wiring layout shown in the above diagram, connect the battery
cable and bridge terminals to the battery poles.
Arrange the cables as shown in the diagram, tighten the terminals on the poles
and cover with Vaseline.
•
Lower the dirty water drum into its work position and fasten it to the detergent tank;
•
When using the machine, follow the instructions below.
