Merlo Tech Talk: Battery ‘Kill’ SwitchApplied Machinery Sales
The battery disengage (some call them ‘kill’) switches on Merlo telehandlers do have a function. Depending on the model of Merlo telehandler, it could be electronic or manual, or not available at all.
Where’s the switch?
Panoramic models with Stabilizers, the battery disconnect is front and almost center.
Newer Rotos, such as the R50.35 S Plus, have the battery disconnect placed front and center within the battery compartment.
Roto 40.30 does not have a kill switch. Neither does the P40.17 with stabilizers.
Why there is a battery disconnect. The one, two answer.
One: to preserve battery life. If the machine will be sitting for a period of time, disengaging the battery ensures when reengaged the machine will fire right up.
Two: for safe maintenance, especially when working on the electronic system. A good practice is to always disengage the battery during any maintenance action.
On the HM and R models, just flip the switch.
On the machines with manual “keys”: push in the key and twist. Counterclockwise disengages the battery and clockwise engages. If so desired, the key can be removed for added safety and battery life preservation, and to ensure the machine cannot be started.
On the newer Rotos, the lite yellow button is a simple push on/push off.
Just one more thing about battery kill switches. Is the machine running DEF?
For machines that will be stored for a couple of or more, days our techs suggest the following: After turning off the ignition, wait (listen carefully) until the pump stops cycling (5 minutes +/-) before disengaging the battery. If you do not wait, upon restarting the engine, an error light will appear, and you may not be getting back to work as quickly as you had hoped.
