1. Replace engine oil and hydraulic oil with those of viscosities suitable for
cold weather.
2. In cold weather, battery power drops, and the battery fluid may freeze if the
battery is not sufficiently charged. To prevent the battery fluid from freezing,
be sure to keep the battery charged at least 75% or more of its capacity after
operation. To ease next starting, it is recommended to keep the battery stored
in closed or heated rooms. If the battery fluid level is too low, do not add
after operation, but add with the engine
running before the next operation.
3. Add anti-freeze to coolant in the radiator and reserve tank, if the ambient
temperature is expected to drop below 32 F (0 C). Mixing
ratio of water and anti-freeze depends on the expected ambient temperature.
However, a 50/50 mix is recommended.
• Mixing ratio between water and anti-freeze
Ambient °C
Temperature (°F)
IMPORTANT:
• Use permanent anti-freeze or long-life coolant.
• Drain the coolant completely and clean the radiator inside then fill with the
water and anti-freeze mixture.
• As the anti-freeze also acts as an anticorrosive, it is not necessary to add
an additive to the water and anti-freeze mixture.
• See "Coolant check" under "DAILY CHECKS" in "MAINTENANCE" for
radiator fill volumes.
PROCEDURE AFTER WORK CARRIED OUT
Clean the excavator thoroughly after work and wipe dry. Otherwise mud and
earth on the crawlers could freeze if the temperature drops below the 32°F (0°
C) mark. Operation of the excavator is then not possible. Store the excavator
in a dry place; if not possible, store on wooden planks or on mats. If the
excavator is kept on damp or muddy ground, the crawlers could freeze
overnight. Operation of the excavator is then not possible. Furthermore the
reduction gear may be damaged.
Additionally, the hydraulic cylinders piston rods must be rubbed dry.
Otherwise severe damage could occur if dirty water seeps through the seals.
LONG STORAGE
CAUTION
To avoid personal injury:
• Do not clean the excavator with the engine running.
• To avoid the danger of exhaust fume poisoning, do not operate the engine in a closed
building without proper ventilation.
• When storing, remove the key from the starter switch to avoid unauthorized persons
from operating the excavator and getting injured.
