Looking for the Daewoo Solar 015 Plus shop manual PDF? This 406-page factory shop manual (OEM #023-00038E) covers the Solar 015 and 015 PLUS track excavators from the pins up: engine, drive train, hydraulics, and electrical. Inside, you get the full hydraulic schematic and electrical schematic, step-by-step teardown procedures for the main pump, swing motor, travel motor, and main control valve, plus a standard torques section that settles shop arguments fast. A full chapter walks you through track assembly and undercarriage service, with boom, arm, and bucket procedures for the attachments. Torque the main cylinder head bolts to 7.5-8.5 kg-m (54-61 ft lb) and pull the 3/4-inch split flanges to 3.0-3.7 kg-m (22-27 ft lb). No more chasing hydraulic leaks with forum guesses. Bookmarked with a full text layer: type the spec, find the page, get back on the tracks.

Daewoo Solar 015 PLUS Common Problems This Manual Covers
Daewoo Solar 015 Plus pulls to one side and will not track straight during travel
Test each side by jacking up one track and comparing travel motor speed. Swap the crossover hoses at the motors; if the drift follows the hoses, service the control valve instead of the motor. Verify motor flow against the 11.7 liters/min spec on page 289, then torque mounting bolts to 5 - 6.5 kg•m.
Manual Section: Hydraulics p. 289Hydraulic pump loses pressure under load, boom and bucket move slowly or stall
Test main relief pressure with a gauge at the pump outlet; P1 and P2 must hold 210.0 kg/cm2 (3,000 psi) per page 346. Check suction pressure next: anything outside -0.02 to +0.1 MPa on page 317 points to a plugged strainer or aeration. If pressure adjusts but drifts back, inspect the pump rotating group for wear.
Manual Section: Hydraulics p. 346Engine cranks slowly or will not start at all in cold weather
Check battery voltage and load-test both cables; corroded positive and negative cables fail often on these machines. Verify charging circuit connections against the wiring diagram on page 376. Confirm engine oil is the correct winter viscosity at the full 4.1 liter capacity, then work through the hard-starting checks in the engine section starting on page 109.
Manual Section: Engine and Drive Train p. 109Tracks loosen and jump off the sprocket when turning on uneven ground
Measure the recoil spring first; free length below 261.0 mm on page 93 means the spring will not hold tension anymore. Inspect sprocket teeth for hooking and retorque the mounting bolts to 6.5 kg•m per page 97. Check track roller hardware while you are under the machine; roller bolts take 21.0 kg•m.
Manual Section: Lower Structure and Chassis p. 93Engine will not start after maintenance, warning tag still attached to controls
Remove the warning tag only after confirming all service work is finished and guards are reinstalled, following the safety instructions on page 9. Check that every lockout is cleared and the controls sit in neutral. Verify fuel level before cranking; the tank holds only 19 liters and runs dry faster than most operators expect.
Manual Section: Safety p. 9Frequently Asked Questions
What are the torque specifications for the engine cylinder head bolts on the Daewoo Solar 015 PLUS?
For the Daewoo Solar 015 PLUS engine, the M10 cylinder head bolts should be tightened to 7.5 - 8.5 kg•m (54 - 61 ft lb), and the M8 bolts should be tightened to 2.0 - 3.0 kg•m (14 - 21 ft lb). p. 125
What are the replacement specifications for the travel motor?
The travel motor (with gear box) has a rated flow of 11.7 liters/min (3.1 gpm) max, and a maximum operating pressure of 20.6 MPa (210 kg/cm2 or 3,000 psi). p. 289
What is the correct valve clearance for the engine?
