• Repair cracks or metal fatigue failures by stop-drilling, welding,
patching or splicing.
•
Prime and paint marred, rusted or damaged finish using a high-
grade primer and finish paint materials.
• Clean areas that are extremely oily or greasy with mineral solvents
and degreasers before painting.

• Check oil level before each use.
•
Change engine oil after first 20 hours of operation and every 100
hours thereafter.
•
Clean air cleaner every 3 months or 50 hours, whichever occurs first.
• Clean sediment cup every 6 months or 100 hours.
• Clean and reset gap on spark plug every 6 months or 100 hours.
• Adjust valve clearance every year.
2.1.3 | Hydraulic System
2.1.3.1 | Hydraulic Oil Tank
The level of hydraulic oil should be checked after every 100 hours of
operation and added as required. Recommended oil is Mobil DTE-13 or
equivalent. Capacity of the tank is 10 U.S. gal. (38 liter).
Always drain and replace hydraulic oil if there is any doubt as to its purity.
Oil should be drained and replaced annually.
2.1.3.2 | Hydraulic Oil Filters
There are two filters in the hydraulic system:
Low Pressure Strainer
– This strainer is located in the tank suction
line outlet. It should be flushed out at each oil change. Remove strainer
straight down from the outside.
Return Line Filter
– This filter is located on the side of the hydraulic tank.
The 10-micron element for this filter must be changed after the first 50
hours of operation and every 250 hours thereafter.
WARNING!
Perform no welding, cutting,
patching etc. on any load-
bearing or support structures.
If such Repairs are necessary,
contact the Engineering Dept.
of Stinar, LLC before making
any alterations.
CAUTION!
Always determine hydraulic
oil level and fill tank to
proper level with all hydraulic
cylinders fully retracted:
otherwise, overfilling could
occur, resulting in possible
damage to tank when system
is operated.
