COLD WEATHER STARTUP
Hydraulic fluid becomes thicker in cold weather. STANLEY
recommends that the engine be run at a low idle (5
GMP/20 LPM setting) long enough to bring the fluid
temperature up to a minimum of 50°F/10°C. Allow the
hydraulic fluid to circulate through the tool hoses until they
are warm.
Once the hydraulic oil is warm, you may operate the HP12
as normal.
