he DEUCE is one tough workhorse, but dirty oil in its hydraulic system can
make it turn up lame in a hurry.
So keep your oil supply covered and protected. Then before you add hydraulic
fluid, wipe off any dirt around the DEUCE’s filler cap. If it’s raining or dusty, use
a clean rag around the oil can nozzle and filler hole while you add oil.
Also be careful when adding oil. The oil can nozzle can tear a hole in the side
of the strainer or knock out its bottom.
Then dirt has a straight path to the tank.
Check out the strainer. If it’s damaged or missing, tell your mechanic.

O
perators,
you don’t have to
replace the 22-ton crane’s primary filter
element every time the restriction indi-
cator shows red.
You can often save the cost of a new
element by cleaning the old one with
compressed air or warm, soapy water.
When you use air, blow out from the
inside of the element, since the dirt’s on
the outside of the filter.
Then hold the nozzle at an angle to
blow loose dirt from the outside. That
keeps you from damaging the paper element.
For oily dirt, use detergent
and warm water
For loose dirt, use compressed air
Finally, replace the cap and snug it down when you’re finished.
Use these oil PM tips and you’ll keep the dirt where it belongs-- out in front of
the blade!
