INTRODUCTION
Service Manual Purpose
This manual is a technical resource that Nilfisk-Advance expects to be utilized when servicing a Condor XL. It contains information deemed neces-
sary to provide basic troubleshooting, maintenance and repairs within a reasonable timeframe (example - 2-3 hours). If your repair involves multiple
visits to repair the same problem, or the repair cannot be completed within 3-4 hours, a call to Nilfisk-Advance Technical Support is needed to alert
the factory to potential issues and/or provide the customer with an acceptable level of service. Refer to the website www.advance-us.com for ad-
ditional information not contained herein as well updates or expanded instructions to procedures noted here.
Note: Bold numbers in parentheses in text indicate an illustrated item.
Note: All references to right, left, front and rear in this manual are as seen from the operator’s position (seat).
General Machine Description
The Condor XL machines are industrial automatic rider sweeper/scrubbers with multiple sweep/scrub single pass coverages. All models use dual
cylindrical scrub brooms with variable scrub pressure and solution flow rates. Different models are available with front mounted side brooms (single
and dual) and right side disc scrub.
Parts and Service
Repair should be performed by an Authorized Nilfisk-Advance Service Center that employs factory-trained service personnel and maintains an
inventory of Nilfisk-Advance original replacement parts and accessories.
Nameplate
See Figure 1. The Model Number and Serial Number of the machine are shown on the nameplate (A) located on the steering column support, and
on a second nameplate (B) beneath the floor plate attached to steering spindle support.

JACKING THE MACHINE
CAUTION!
Never work under a machine without safety stands or blocks to support the machine.
When jacking the machine, do so at designated locations. See Tie Down/Jacking Locations (C) in Figure 2.
TRANSPORTING THE MACHINE
CAUTION!
Before transporting the machine on an open truck or trailer, make sure that:
 All access doors are latched securely.
 The machine is tied down securely. See Tie Down/Jacking Locations (C) in Figure 2.
 The machine Parking Brake (28) is set.
TOWING OR PUSHING A DISABLED MACHINE
CAUTION!
The machine’s drive propelling pump is manufactured with an adjustable tow valve. This valve prevents damage to the hydraulic
system when the machine is being towed/pushed short distances without the use of the engine.
See Figure 3. The tow valve is controlled by the Tow Valve Lever (34) which is accessed by opening and propping up the Engine Cover (3). Pull
the Tow Valve Lever out to disengage the hydrostatic lock between the motor and pump.
The hydrostatic pump can be damaged if the machine is towed with the valve in the normal working position (Tow Valve Lever pushed IN). Note: If
the tow valve is left in free-wheeling position (Tow Valve Lever pulled OUT) the hydrostatic pump can’t drive the machine FWD or REV. No damage
will result, just reset the valve to the normal working position by pushing the lever IN. Tow or push the machine no faster than a normal walking pace
(2-3 miles per hour) and for short distances only. If the machine is to be moved long distances, the front drive wheel needs to be raised off the floor
and placed on a suitable transport dolly.

MAINTENANCE
HYDRAULIC OIL
Open and prop the Engine Cover (3) to access the hydraulic oil reservoir. Remove the Fill Cap (44) from the tank and look to the bottom of the filler
screen. If the oil level is below the bottom of the filler screen, add 10W-30 motor oil until the bottom of the filler screen is covered. (The oil level
should not be higher than 1/2” (12.7mm) above the bottom of the filler screen.) Change and flush the oil if major contamination from a mechanical
failure occurs.
ENGINE MAINTENANCE
ENGINE OIL – GASOLINE / PETROL AND LPG
Check the engine oil level when the machine is parked on a level surface and the engine is cool. Change the engine oil after the first 35 hours
of operation and every 150 hours after that. Use any SF or SG rated oil meeting API specifications and suited to seasonal temperatures. Refer
to the engine manufacturers’ service manuals for oil capacities and additional engine specifications. Replace the oil filter with every oil change.
TEMPERATURE RANGE OIL WEIGHT
Above 60° F (15° C) SAE 10W-30

ENGINE OIL – DIESEL
Check the engine oil level when the machine is parked on a level surface and the engine is cool. Change the engine oil after the first 35 hours of
operation and every 150 hours after that. Use CF, CF-4 or CG-4 oil meeting API specifications and suited temperatures.
*Important: Reference the oil/fuel type note below for further diesel oil recommendations. Refer to the engine manufacturers’ service manuals for
oil capacities and additional engine specifications. Replace the oil filter with every oil change.
TEMPERATURE RANGE OIL WEIGHT

* Diesel Lubricating Oil Note:
With the emission control now in effect, the CF-4 and CG-4 lubricating oils have been developed for use with a low-sulfur fuel used in on-road vehicle
engines. When an off-road vehicle engine runs on a high-sulfur fuel, it is advisable to employ the CF, CD or CE lubricating oil with a high total
base number. If the CF-4 or CG-4 lubricating oil is used with a high-sulfur fuel, change the lubricating oil at shorter intervals.

SPECIAL LIQUID PROPANE FUEL SYSTEM MAINTENANCE ON THE GM 1.6L ENGINE
Every 150 hours inspect and drain any oil buildup from the LP fuel system electronic pressure regulator (EPR). During the course of normal opera-
tion, oils or “heavy ends” may build inside the chambers of the propane regulator. These oils and heavy ends may be a result of poor fuel quality,
contamination of the fuel supply chain, or regional variation in the makeup of the fuel. If the oil buildup is significant it can affect the function of the
fuel control system. Note: Reference the Tier 2 PSI 1.6l PFI certified engine service manual, form # PSI1P6LPFI-A, and follow the procedure to
drain the EPR regulator.

MAINTENANCE
ENGINE COOLANT
CAUTION!
Do not remove the radiator cap when the engine is hot.
To check the engine coolant level, open and prop the Engine Cover (3) and observe the coolant level in the Coolant Overflow Tank (6). If the level is
low, add a 50/50 mix of water and the recommended type antifreeze. Clean the radiator and oil cooler exteriors by washing with low-pressure water
or using compressed air every 150 hours. Service Note: The oil cooler tips out for easy cleaning.
ENGINE AIR FILTER MAINTENANCE
Check the Engine Air Filter Service Indicator (5) before each use of the machine. Do not service the air filter unless the red flag is visible in the
service indicator.
CAUTION!
When servicing the engine air filter elements, use extreme care to prevent loose dust from entering the engine. Dust can severely
damage the engine.
The engine air filter contains a Primary (outer) and a Safety (inner) filter element. The Primary Element can be cleaned twice before being replaced.
The Safety Element should be replaced every third time that the Primary Filter Element is replaced. Never attempt to clean the Inner Safety Element.
To clean the Primary Filter Element, unsnap the two clips at the end of the air filter and remove the end housing. Pull the primary element out. Clean
the element with compressed air (maximum pressure 100 psi) or wash it with water (maximum pressure 40 psi). DO NOT put the element back into
the canister until it is completely dry.

drain before purging because a small amount of detergent will be dispensed in the process.
To Purge When Changing Chemicals (the scrub system
must be off):
1Disconnect and remove the detergent cartridge.
2Turn the key switch (50) on and wait a few seconds for
the start-up sequence to finish.
3Press and hold the detergent switch (61) for approxi-
mately two seconds.
4Release the switch when the chemical purge icon (E) ap-
pears on the display and the indicator on the detergent
switch (61) starts flashing.
Note: Once activated, the purge process takes at least 10
seconds. See the illustration on this page for Detergent
System indicators. Normally one purge cycle is adequate to
purge the system.
To Purge Weekly (the scrub system must be off):
1Disconnect and remove the detergent cartridge.
2Install and connect a Cartridge filled with clean hot water.
3Turn the key switch (50) on and wait a few seconds for
the start-up sequence to finish.
4Press and hold the detergent switch (61) for approxi-
mately two seconds.
5Release the switch when the chemical purge icon (E) ap-
pears on the display and the indicator on the detergent
switch (61) starts flashing.
Note: Once activated, the purge process takes at least 10
seconds. See the illustration on this page for Detergent
System indicators. Normally one purge cycle is adequate to
purge the system.
Note: The Detergent Box (C) has Detergent Level Viewing
Slots (D) for referencing the amount of detergent remaining
in the cartridge(s). When the detergent level is nearing the
bottom of this slot, refill or replace the cartridge(s).
To Change the Detergent Mix Ratio (the scrub system
must be on):
1Press and hold the detergent switch (61) for two seconds.
2Release the switch once the detergent switch light begins flashing.
3While the light is flashing, press and release the detergent switch to select the next detergent mixture ratio. Once the desired ratio is selected,
the detergent system will return to normal operation within three seconds.
Note: The detergent mixture (F) will be displayed for approximately 10 seconds each time the scrub mode changes, or each time the detergent
switch is pressed. Once set, the detergent flow rate automatically increases and decreases with the solution flow rate, but the detergent mix ratio
will remain the same. If an operator would prefer the flexibility of setting different detergent dilutions ratios for different solution flow rates, this
specific programming option can be found in the Appendix.
Note: During scrubbing, the detergent system can be turned off at any time by pressing the Detergent ON/OFF Switch (61) to allow scrubbing with
water only. No detergent is dispensed until the scrub system is activated and the Drive Pedal (29) is pushed forward.
Service Note: Follow the “To Purge Weekly” instructions above if the machine is going to be stored for an extended period of time, or if you plan
to discontinue use of the detergent (AXP) system.
