Daewoo Solar 220LL, Solar 290LL Common Problems This Manual Covers
Daewoo Solar 220LL main pump whining under load, engine bogs down, bucket and arm slow
Check reservoir oil level and drain a sample from the pump case; metallic particles mean internal wear, not an adjustment issue. Verify main relief pressure reaches 330 kg/cm2 at the test port, the normal setting listed on page 43. Inspect the suction line for air leaks and confirm the 177 micron intake strainer, page 195, is not clogged.
Manual Section: Main Pump Troubleshooting p. 368All hydraulic functions slow and weak once oil warms up, no unusual pump noise
Check pilot pressure at the pump first; spec is 40 ±5 bar (580 ±73 psi) on page 202. Low pilot pressure starves the control valve spools and slows every function at once. Replace the 10 micron return line filter, page 195, and inspect drained oil for water or grit before condemning the pump.
Manual Section: Hydraulic System Troubleshooting p. 202Track keeps derailing or eating sprockets and rollers, tension adjustment will not hold
Measure link pitch across four links with the track tight; new spec is 190.0 mm (7.48 in.) per pitch on page 143. Check grouser height against the 35.0 mm (1.38 in.) new dimension on page 146 and replace shoes at 25.50 mm (1.0 in.). Inspect the grease tension cylinder seal if adjustment keeps bleeding down.
Manual Section: Lower Structure and Chassis p. 143Engine cranks slowly or will not start in cold weather, batteries test good
Clean and tighten both battery ground cables at the frame before replacing anything. Hold the key in preheat for the full 3.5 seconds, page 517, before cranking in cold weather. Test battery voltage under cranking load, then measure voltage drop across the starter cable; a big drop points to corroded connections, not a bad starter.
Manual Section: Electrical System Troubleshooting p. 517Swing drive howls and runs hot, oil seeping from the reduction gearbox base
Drain the swing reduction gearbox and inspect the oil for metal flakes or a burnt smell. Refill with exactly 6 liters of gear oil, page 137; overfilling churns and overheats, underfilling starves the upper bearing. Replace the base seal if weeping continues and check swing bearing play while the housing is drained.
Manual Section: Swing Reduction Gearbox Troubleshooting p. 137Frequently Asked Questions
How do I clear fault codes on a Daewoo Solar 220LL?
To clear a malfunction code, first correct the underlying problem. Once the issue is resolved, turn the start switch from the 'OFF' position to the 'ON' position to reset the system. p. 558
What is the fuel tank capacity for the Solar 220LL?
The fuel tank capacity for the Solar 220LL is 310 liters (81.9 U.S. gallons). p. 101

The tightening torque for the main relief valve cap (4) on the main control valve is 10.0 kg•m (72.33 ft lbs). p. 429
What is the procedure for bleeding air from the fuel system on a Solar 220LL?
To bleed the fuel system, loosen the plug on top of the fuel filter head. Pump the hand-operated primer pump located by the fuel injection pump until fuel appears at the plug hole, then tighten the plug. Continue pumping until strong resistance is felt, then screw the primer pump knob back into the housing. p. 108
