Merlo Tech Talk: Block Heaters
Merlo telehandlers and DBM mini mixers distributed by AMS-Merlo have as standard, block heaters.
Knowledge Refresher
The term Block Heaters has evolved into a generic term derived from a heater placed in the lower part of the engine or block. It now refers to all added engine heaters, not just those that are installed directly into the block.
Currently, Merlo has the following configurations:
Deutz Engines:
in-hose line
Kohler Engines:
in block
FPT Engines:
in block
How it works
Plugged into a standard, 110V outlet with ground, block heaters act as a heating pad to keep the oil, (and because metal transfer temperatures, other fluids also) warm for easy starts when temps are very cold. The battery does not have to work as hard to get the engine turned over as fluids are, well, fluid.
Fall and Winter Seasonal Maintenance
Before it gets very cold, as a part of your seasonal maintenance, find the block heater plug (usually zip tied to the block/frame when it comes from the factory.) The cord is hard wired to the heater.
We suggest the following steps:
Plug the heater into a 110V grounded outlet at the end of a work day and unplug in the morning before turning the key. It only needs a few hours to do its thing.
Idea: Setting up a timer to go on some hours before you head out the door will save on energy costs.
Before you move the machine, find a way to remind yourself to:
A: UNPLUG the heater before you turn the key
B: TIE UP the cord out of the way of moving parts
Out of season (Spring & Summer)
A: Block heaters are permanently installed
B: Zip tie the cord securely to keep it out of the way of moving parts
