Engine oil recommendations
AKCELA NO. 1 ENGINE OIL 15W-40 is recommended
for use in your machine's engine. The recommended
oil will lubricate your engine correctly under all operating
conditions. If the recommended oil is not available in a
multi-viscosity grade engine oil, it is okay to use a single
grade engine oil in the recommended oil brand.
If the recommended engine oil is not available in multi-
viscosity or single grade, only use oil meeting API engine
oil service category CH-4.
RCPH10TLB244ACL 1
Refer to the chart for recommended viscosity at ambient
air temperature ranges.
NOTE: Do not put Performance Additives or other oil ad-
ditive products in the engine crankcase. The oil intervals
given in the operators manual and service chart are ac-
cording to tests with CASE AKCELA lubricants.

Dye and black light procedure for detecting oil leaks
Oils and grease have natural phosphors and will illuminate differently under the black light. Oil, bluish-white, grease,
brilliant-white, anti-freeze, greenish-yellow, sealing compounds, red to orange.

NOTE: Each dye is formulated to work in conjunction with a specific fluid, therefore the dyes are not interchangeable
and should only be used as described.

INTRODUCTION
1. Prior to adding dye, connect the black light to the
machines battery and investigate suspected areas.
2. Once suspected leak areas are found, attempt to
trace the leak completely to the origin.
NOTE: At the origin, the leak should be the brightest
in color.
3. After confirmation of the suspected leak, thoroughly
clean the area of the leak to remove any existing flu-
ids. Recheck the area with the black light to assure
the area is clean. Good cleaning is important for the
following reasons:
• Fluids captured by threaded joints or other
cavities will continue to show signs of leakage
unless completely clean.
• Casting surfaces can hold residual oil.
RCPH10TLB245ACL 3
4. Use the entire contents of the bottle of dye in the
system/systems of the suspected leak.
5. Run the unit for 5 to 10 minutes and cycle through
suspect system functions to ensure that the dye is
available to all possible leak points.
NOTE: The hydraulic oil should be heated to 71 °C
(160 °F), engine at normal operating temperature,
and transmission should be in the normal operating
range on the gauge.
6. Use a clean cloth and wipe the dipstick or the inside
surface of the filler tube on each of the 3 sumps.
7. View traces of dyed fluid on the cloth under the black
light to ensure good samples.
8. Use these 3 samples as your baseline when inspect-
ing the unit with the black light.
NOTE: High hour engine oil can reduce the effec-
tiveness of the dye. In this event change the oil.
9. Avoid common errors.
• Fan airflow blowing leaking fluid.
• Gravity pulling leak paths down.
• When paint at a joint is not broken, the joint is
not leaking.
NOTE: It is not necessary to change oils after this
check.

INTRODUCTION
Diesel fuel
Use No. 2 diesel fuel in the engine of this machine. The
use of other fuels can cause the loss of engine power and
high fuel consumption.
In very cold temperatures, a mixture of No. 1 and No. 2
diesel fuels is temporarily permitted.
NOTICE: See your fuel dealer for winter fuel requirements
in your area. If the temperature of the fuel is below the
cloud point (wax appearance point), wax crystals in the
fuel will cause the engine to lose power or not start.
The diesel fuel used in this machine must meet the specifi-
cations in the chart or Specification D975-81 of the Amer-
ican Society for Testing and Materials.
Specifications for acceptable No. 2 Diesel Fuel
API gravity (minimum) 34
Flash point (minimum) 60 °C (140 °F)
* Cloud point (maximum) -20 °C (-4 °F)
* Pour point (maximum) -26 °C (-15 °F)
Viscosity (at) 88 °C (190 °F)
Centistokes (2.0) to (4.3)
Saybolt Seconds Universal (32) to (40)
* Refer to the Notice on this page.
Fuel Storage
If you keep fuel in storage for a period of time, you can get
foreign material or water in the fuel storage tank. Many
engine problems are caused by water in the fuel.
Keep the fuel storage tank outside and keep the fuel as
cool as possible. Remove water from the storage con-
tainer at regular periods of time.
