MACHINE OPERATION
SY60C Excavator OMM
Cold Weather Operation
Operating Fluids in Cold Weather
When operating the machine in low temperatures, the
engine may be difficult to start, the fuel lines may freeze,
and oil may become more viscous. Select fuels and
lubricants according to the air temperature.
See “Recommended Lubricants, Fuel, and Engine
Coolant” on page 5-7.
Battery in Cold Weather
WARNING
Before proceeding with any battery maintenance
procedure, observe the following precautions:
• The top of the battery must be kept clean to
prevent plugging of the battery vents. Regularly
wash the top of the battery to prevent the battery
vents from plugging.
• Battery gases are explosive. Never smoke
around batteries or expose them to sparks or
open flames. Work in a well-ventilated area.
• Wear personal protective equipment (PPE) when
working with batteries.
• Battery acid can cause burns or injury. If battery
acid makes contact with your skin or eyes, flush
the area immediately with fresh water and seek
medical attention.
Failure to follow this warning could result in death
or serious injury.
In cold climates, battery efficiency will decline. Electrolyte
can freeze if the battery charge is low. Keep the battery
charged near 100% and in a warm area if possible.
After Daily Operation
Mud and water accumulation on the undercarriage can
affect normal operation of the machine. Make sure to
perform the following actions after daily operation:
• Remove mud and water from the machine. Mud, dirt,
and water can damage the seals.
• Park the machine on a firm, dry surface.
• If possible, park the machine on boards, which can
prevent the tracks from sinking into soft ground.
Normal operation can fail if the machine becomes
stuck.
• After operating the machine in water or mud, perform
the following procedures to drain water from the
undercarriage to extend its service life:
1.
Run the engine at low speed and swing the upper
structure 90° so the work equipment is sideways.
WARNING
Rotating tracks are dangerous. Stay away from
rotating tracks. Failure to follow this warning
could result in death or serious injury.
2.
Raise the machine so that one side of the tracks is off
the ground. Remove mud buildup by operating the
lifted track forward and backward.
NOTICE!
Fill the fuel tank to its maximum level after
operation to prevent moisture in the fuel tank
from condensing.
3.
Fill the fuel tank.
Machine Storage in Cold Weather
• Clean the machine.
• Check the engine coolant and engine oil levels, and
check for leaks. The machine is normally filled to
withstand a minimum low temperature of -40°F (-40°C).
Change the fuel, coolant, engine oil, hydraulic oil, and
gear oil with new fluids that meet the air temperature
requirements as necessary. See “Recommended
Lubricants, Fuel, and Engine Coolant” on page 5-7.
• Check the machine for leaks. Check all cylinder rods
for scratches and corrosion. Apply grease to exposed
cylinder rods.
• Remove and charge the battery. When the battery is
fully charged, store it indoors.
• Install the battery and start and run the machine on a
monthly basis.
• Clean the battery terminals as necessary. Apply a coat
of dielectric grease to the terminals.
After the Cold Season
Replace the fuel and engine oil with fuel and oil of the
specified viscosity. See “Recommended Lubricants, Fuel,
and Engine Coolant” on page 5-7.
NOTE:
If permanent ethylene glycol engine coolant was
not used and ethanol engine coolant is used as an
alternative, drain and flush the cooling system
completely and add new ethylene glycol engine
coolant to the cooling system.
